Chaîne articulée de 40 maillons clipsables
Created today
Description
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.

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.
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.
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.
Chubby Sitting Hamster Keychain
A compact, sitting hamster figure modelled with exaggerated, rounded proportions for a chunky silhouette. The base is sheared flat to allow support-free printing directly on the build plate, and a reinforced loop is integrated into the upper back of the head. Dimensions: ~28mm wide, 30mm tall. Keyring Loop: 3.2mm horizontal bore, heavily chamfered outer ring. Print Settings: Print upright. The limbs and facial features intersect closely with the main body to minimise overhangs; no supports are required.
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.
