Chaîne articulée de 40 maillons clipsables
Une chaîne imprimée d'un bloc se désassemble au moindre effort, et une chaîne trop courte ne sert à rien. Cette version aligne 40 petits maillons à rotule, à clipser à la main pour obtenir une chaîne d'environ 190 mm. Chaque maillon a une rotule d'un côté et une douille à quatre pétales de l'autre. Les pétales plient au passage de la rotule puis se referment, ce qui laisse la chaîne se plier dans toutes les directions et se démonter sans outil. Chiffres utiles Largeur d'un maillon : 4,6 mm Pas entre maillons : 4,8 mm Longueur assemblée : environ 190 mm (40 maillons) Jeu théorique : 0,15 mm par côté, à ajuster selon l'imprimante Impression : maillons à plat, en deux colonnes de 20, sans supports Matériau conseillé : PETG, plus tolérant que le PLA pour les pétales fins Buse 0,4 mm, hauteur de couche 0,12 à 0,16 mm
Micro Print-in-Place Joystick
This is a print-in-place ball joint that acts as a miniature thumb joystick. The entire assembly prints as one welded-together block with an internal 0.4 mm gap; once it's off the build plate, a firm snap frees the stick to rotate and swivel in the base. It is designed to be as small as FDM printers can reliably manage without snapping the stalk.
Minimalist Concert Ola Keychain
A sleek, minimalist keychain bearing the word "ola" in the Concert One font. The lowercase letters are gently thickened to form a continuous, sturdy body, finishing in a small heart on the right side. Design Features Integrated Keyring Tab: A reinforced loop in the top-left corner is ready for standard split rings. Continuous Body: Offset text creates a solid, unified piece that prints securely and cleanly. Friendly Silhouette: The Concert One typeface combined with a minimal heart provides a smooth, tactile feel.
Fluier Cochilie Spiralată
Un fluier cu siluetă de cochilie de mare: camera rotundă poartă o nervură în spirală, iar muștiucul scurt iese în față ca un cioc. Aerul trece printr-un canal îngust, lovește muchia ascuțită din fereastră și face camera să sune. Cameră de rezonanță cilindrică, închisă Inel pentru breloc în spate Nervura spiralată se poate imprima într-o altă culoare Se printează culcat, fără suporturi; stratul de 0,2 mm dă un sunet curat
Fidget
What it's for A fully print-in-place fidget roller inspired by continuous-motion hand toys. It features two heavily grooved outer cylinders captured on a rigid internal frame. Built to be rolled continuously in one hand to keep fingers busy. Dimensions Overall size: 37 mm wide, 63 mm tall, 22 mm deep. Rollers: 22 mm diameter, 50 mm tall with 20 scalloped grip grooves. Clearance: Designed with a 0.5 mm gap top, bottom, and radially around the axles for a free spin immediately off the build plate. Print notes Prints completely vertically without supports. The top frame link is designed with a flat bottom to bridge cleanly across the two internal axles without adhering to the rollers beneath it. Once finished, a firm twist breaks any minor stringing and frees the rollers.
Sifflet Tactique Double Chambre
Un sifflet de survie compact et puissant, construit autour d’une architecture à double chambre. Imprimable sans aucun support, il utilise deux cavités de résonance de longueurs différentes pour générer une dissonance acoustique perçante. Pour les remixeurs Ce design est purement mathématique et conçu pour être ajusté : Pitch et Dissonance : La longueur des chambres (actuellement 41 mm et 47 mm) dicte la fréquence. Raccourcissez-les pour un son plus aigu. Coupe du sifflet (Fipple) : L'angle de la rampe est fixé à -18 degrés et le bord d'attaque divise le flux d'air à Z=11.0. Si votre imprimante a tendance à sur-extruder, ajustez la hauteur de la fenêtre de frappe pour garantir que l'air ne soit pas étouffé. Grips : Les rainures latérales et supérieures sont de simples soustractions itératives, faciles à remplacer par des logos ou du texte plat.
montr 2
What it's for A streamlined, one-piece 50 mm watch case with a 22 mm lug width. The edges have been significantly rounded for a softer, more refined profile on the wrist. Features a classic coin-edge bezel aesthetic with engraved minute markers and an inverted triangle at 12 o'clock. Dimensions Overall Case: 50 mm diameter, 8 mm thickness Inner Cavity: 36 mm diameter, with a solid 2 mm base floor Lugs: 22 mm spacing, slightly thinned for a dressier look Assembly Standard 22 mm spring bars will fit the 1.3 mm lug holes. The central cavity is a straight cylindrical fit, ready for a 36 mm movement or a custom dial insert.
550 Paracord Mini Camera Bead
A miniaturized camera bead designed to fit standard 550 paracord. The body has been scaled down for a tighter profile on lanyards or zipper pulls, while maintaining the exact bore needed to thread over the cord. Bore: 3.5mm (fits standard un-gutted 550 paracord). Dimensions: 12mm wide by 8mm tall. Assembly: Built as a single solid mesh with distinct geometric regions, making it simple to assign silver and black colors in your slicer without manual painting.
Pocket Multi-Fidget Block
What it's for A dense, multi-function pocket fidget block that packs six tactile mechanisms into a single footprint. Designed to be printed entirely flat without supports, it features a print-in-place captive joystick, a spinning side-wheel, and two cantilevered clicky buttons. The front edge houses a deep hidden storage slot containing a flat-packed basketball kit. The backboard (complete with a rubber band hook on the rear) slots into the top of the block, and the rim snaps firmly into the backboard. Finally, one quadrant contains an internal hollow tank cavity with a threaded fill plug and a side spout. The top wall of the tank is intentionally thin (0.8mm) with a tactile button pad—pressing it lightly flexes the roof, simulating a squirt-pump mechanism. (While functional in TPU, printing in PLA serves as a satisfying, slightly yielding fidget button). Dimensions Base Block: 60 × 60 × 18 mm. Storage Slot: 46 mm wide, 58 mm deep, 4.5 mm tall. Backboard: 30 × 25 mm (excluding base peg). Rim: 18 mm outer diameter. Assembly Print Settings: No supports required. Ensure your printer is dialed in for 0.4mm print-in-place tolerances so the joystick and spinner break free smoothly. Hoop: Slide the backboard out of the front slot, insert the peg into the slot on the top deck, and press the rim peg into the backboard hole. Tank: The included friction plug seals the top fill hole.
25mm Split Ring Registration Plate
Solid registration plate built to clear standard 25mm split rings. The 4.5mm bore is strictly for split rings or small carabiners; it will not accept wide webbing or thick lanyards. Print Specs Footprint: 80mm x 20mm Base Plate: 2.4mm thick. Embossed Details: Text and border sit 0.8mm above the face. Stop the print at 2.4mm Z-height to swap colors.
Simao Split-Ring Tag
Standard rectangular tag drilled for a 5 mm split-ring. Dimensions to check: Fits standard 20 mm to 30 mm key rings. Clearance bore is 5 mm. Overall length 60 mm, thickness 4 mm including the raised lettering. Does not include chamfers for sliding into tight leather key wallets. Matches Simao.

Keyring Loop Registration Plate
Registration plate tag, scaled for a standard keychain layout. Mating Surface: 5mm bore fits standard split rings or small wire carabiners. Geometry: 80x26mm overall footprint with a flat 2.4mm back to sit flush against other keys. Clearances: The border and text sit 1.2mm proud of the base plate, allowing for a mid-print filament swap if printed horizontally on a single-extruder machine.
Bouquet Initial Keychain
What it's for A personal keychain built with raised script initials framed by an asymmetrical floral arrangement. The flowers cluster heavily at the base and taper up the sides in a crescent bouquet, leaving the top mount area clean and open. Dimensions Base diameter: 44 mm Plate thickness: 2.5 mm Relief depth: Initials and flowers stand 1–1.5 mm proud of the base Print notes Standard 0.2 mm layers work well; no supports required. The raised elements are flat-topped to make an intentional filament swap cleanly separate the base colour from the text and flowers.

VortexCore — Inel Giroscopic
Un model giroscopic compact format din patru elemente concentrice, creat pentru a fi imprimat direct articulat. Fără asamblare posterioară. Pivoții conici sunt calculați la o toleranță generoasă, permițând fiecărui inel să se rotească liber pe axa sa de îndată ce este ridicat de pe patul de imprimare. Dimensiuni Diametru total: 60 mm Înălțime: 10 mm Toleranță îmbinări: ~1.2 mm diametral Detalii de printare Se printează fără suport (no-supports). Designul pivoților folosește unghiuri de 45 de grade specifice printării FDM în sistem print-in-place, garantând că sferele interioare nu necesită susținere suplimentară pe axa Z. După finalizare, este suficientă o ușoară presiune pentru a dezlipi inelele unele de altele.
Print-in-Place Tri-Wheel Fidget
What it's for A captive, fully print-in-place mechanical fidget toy. It features three deep-treaded thumb wheels trapped within rounded U-brackets at the corners, plus a central rotating hub. The entire assembly drops onto the build plate as a single unit and breaks free immediately after printing. Dimensions Overall footprint: ~88 mm point-to-point. Thickness: 16 mm frame (top hub cap sits 1.5 mm higher). Clearance: 0.4 mm gap around all moving parts. Print notes Designed for PLA with no supports. Elephant-foot compensation chamfers are built directly into the bottom faces of the captive axles and the center hub hole, ensuring the mechanisms won't fuse to the build plate on the first layer.
Carteira Rígida para Moedas e Notas
Moedas soltas destroem bolsos, e notas amassadas se perdem no fundo da mochila. Carteiras de couro tradicionais não resolvem o problema quando o que você precisa é de estrutura. Esta é uma carteira rígida com tampa deslizante para manter tudo no lugar. O compartimento principal tem o tamanho exato para cartões de crédito e notas dobradas, enquanto uma divisória dedicada trava as moedas na parte de trás para que não se misturem nem façam barulho. Detalhes de Impressão e Ajuste Dimensões Internas: Área de cartões/notas com 90x69 mm; área de moedas com 26x69 mm. Mecanismo: Tampa deslizante com trava de fim de curso e ranhuras para o polegar. Tolerância: O trilho deslizante tem uma folga de 0.4mm ao redor da tampa para deslizar suavemente direto da impressora. Impressão: Imprima as duas peças planas na mesa. Não requer suportes.
Cierre Escalonado para Cinta 25mm
Un cierre mecánico de dos piezas diseñado para pulseras o correas hechas con cinta plana de 25 mm de ancho. El diseño utiliza un sistema de solape escalonado con tres pestañas de retención. Configuración del pase: 3 ranuras paralelas de 2.5 x 26 mm por lado, pensadas para entrelazar la cinta con firmeza. Mecanismo: Unión tipo solape (lap joint) con retenes de fricción esféricos; encaja a presión y resiste tensión lateral. Tolerancias: El cierre incorpora 0.3 mm de holgura exacta en las cavidades hembra para un ajuste perfecto en máquinas FDM bien calibradas. Impresión: Ambas mitades descansan planas sobre la cama. No requiere soportes.
Closed-Sleeve Glasses Ear Hooks
Straight diagonal ear hooks with a closed, slip-on sleeve design. They act as anchors behind the ear to keep frames from sliding down when looking forward or down. Adjustments for a perfect fit The internal sleeve: Currently set at 2.5mm width and 5.0mm height. This works for most standard wire or thin acetate frames. Thicker plastic frames will need these bumped up. The drop angle: The rear sphere is dropped back and down to catch the ear. You can tweak the position of the tail end to hug a specific ear shape tighter. Material choice: TPU or another flexible filament works best here for grip and comfort, though PLA will work if the friction fit is precise.
Mechanical 40-Quarter Dispenser
A fully mechanical, gravity-fed coin magazine tailored for standard U.S. quarters. Designed to slip into a pool cue bag, it stores a full $10 roll vertically and cleanly dispenses exactly $1 (four quarters) per cycle into the palm of the hand. The mechanism relies on a two-stage sliding escapement. In the resting position, the bottom four coins sit perfectly flush inside the 7.2mm-thick slider pocket. When the thumb tab is pulled outward, a chamfered ramp on the top trailing edge of the pocket catches the fifth quarter and guides it smoothly onto the solid tail of the slider, suspending the rest of the stack. Once the pocket aligns with the drop chute at full extension, the isolated four quarters fall through. A captive printed pin mounted from the base runs in an internal track on the slider, acting as a hard travel limit for both the pull and return strokes. Design Features Threaded Cap: The top of the magazine tube features a coarse 4mm-pitch thread, securing the cap firmly for travel. Clearance-Tested Slot: The stopper pin track is positioned well behind the coin pocket to ensure no interference with the resting quarters. Coin Bore: Sized at 25.2mm to allow smooth gravity feed for a 24.26mm quarter. Slider Geometry: The 7.2mm thickness dictates the exact four-coin dispense count.
Aegis — Symmetrical Barrel Plaque
A precisely dimensioned rectangular charm featuring gently rounded edges and delicate engraved details. Designed to lie perfectly flat while capturing intricate central motifs. Features Dimensions: 38.10 mm × 16.10 mm × 4.57 mm Top-to-Bottom Passage: A clean 3 mm cylindrical tunnel runs completely inside the narrow vertical profile. Surface Art: Features a recessed shield, twin vertical channels, and a soft continuous curved arc near the base.
60mm Print-In-Place Concentric Gyro
A four-ring concentric gimbal toy designed for fully assembled printing. The rings pivot independently on alternating axes using built-in conical hinges. All exterior edges are rounded for comfort. Clearances: 0.5 mm radial and axial gap between all moving surfaces. Overhangs: Conical pivots operate at a 45-degree angle, requiring no supports. Base: Rings are coplanar at z=0 to ensure solid bed adhesion. Dimensions: 60 mm outer diameter, 12 mm overall thickness.
