Orbital Gyro Fidget
A four-stage concentric gyroscope built to spin freely straight off the build plate. The rings alternate their pivot axes, allowing the core to tumble smoothly in three dimensions while the outer frame stays anchored in the hand. The clearances are set tight enough to keep the action crisp, but loose enough to break free with a single twist after printing. Construction Details Print-in-Place: Internal spherical pivots bridge the air gaps without requiring supports. Tolerances: Features a uniform 1.5mm air gap between rings and 0.5mm radial clearance on all internal ball joints. Edges: Chamfered top and bottom profiles prevent elephant's foot from fusing the rings and offer a softer feel.
Eyeless Alien Duck Keychain
Small keys vanish into the depths of bags when left loose. This chunky bath duck acts as an anchor to prevent them from slipping out of reach. It features a bulbous alien-proportioned head, dual antennas, and a completely featureless face for a distinct silhouette. Sizing and Setup Overall height: 47 mm Mounting: 5 mm integrated loop for standard split rings Printing: Flatted base sits flush on the bed; prints as one solid piece.

Enclosed Auto-Return Clicker
An enclosed, print-in-place mechanical clicker with a dedicated auto-return spring. The internal mechanism is fully hidden, leaving just the thumb lever exposed for a cleaner look and a protected mechanism. Internal Clearance: Prints with a 0.5mm gap between the top roof and the lever, letting it move freely straight off the bed. Enclosed Shell: Total height is bumped to 11mm to give room for the solid 1.5mm top and bottom walls. Remix Hooks: The internal spring thicknesses (1.0mm for the click, 1.2mm for the return) dictate the feel. Thin them by 0.2mm for a much lighter touch, or increase the internal height if you want to experiment with deeper cams.
Round Tuit Dual-Sided Token, V 1
A 50 mm dual-sided token featuring bold raised text on the front and flush, mirrored text inlaid on the back. Designed to be printed flat on the bed, using contrasting colours to make the details pop. Front: Raised "Round TUIT" text Back: Flush-inlaid "3DP@GIRTON.ORG" text Dimensions: 50 mm diameter, 3 mm base thickness
Stenhus Gymnasium Nøglering
En robust nøglering med Stenhus Gymnasiums navn sat op i blok-format (hvor linjerne er tvunget til samme bredde), og et dedikeret svunget bølge-symbol i venstre side med vandrette afskæringer i top og bund. Mål: Basen er 90 x 30 mm med afrundede hjørner og et forstærket hul til nøgleringen. Relief: Både tekst og logo løfter sig diskret 0,6 mm fra basen, hvilket giver et skarpt print uden at det griber for meget fast i lommen. Tekst: Ordene er sat med Roboto, hvor bunden er skaleret for at give et balanceret, tungt udtryk.
Captive-Pea Emergency Keychain Whistle
A 50mm print-in-place emergency whistle built around a 12mm spherical resonating chamber. It features a tapered mouthpiece and an integrated 7mm captive pea that creates a high-decibel warble, all packed into a low-profile keychain block. Remix Hooks & Constraints Chamber Geometry: The fundamental tone is dictated by the 12mm sphere. Expanding this chamber lowers the pitch, while shrinking it creates a sharper, higher shriek. Captive Pea: The 7mm pea prints with a 0.2mm floor gap. This clearance is just tight enough to prevent the sphere from tearing off the build plate, but weak enough to break free with a pen tip. Windway & Fipple: The air channel is fixed at 1.5mm high to compress the airstream before it hits the 45-degree splitting edge. Changing the fipple angle will dramatically alter the sound quality. Mounting Loop: The 5mm bore at the rear fits standard split rings and 550 paracord. If scaling the model for a heavier carabiner, reinforce the tail block first.
Chunky Modern Type Keychain
A solid, pocket-sized keychain featuring a custom typographic design. The base perfectly contours the bold lettering, creating a clean and modern silhouette that feels sturdy in hand. Pocket-Friendly Size: Scaled down to slide easily into a pocket without snagging. Sturdy Build: A solid 5 mm base prevents flexing, with 2 mm raised lettering that holds up to daily wear. Ready to Mount: Features a fully through 5 mm keyring hole to accommodate standard rings or small carabiners.
Overwatch — Event Badge Holder
A rigid, oversized vertical credential holder built to exactly 5.5 × 3.5 inches footprint. It features a central thumb cutout to let you quickly pop the badge out when needed, while retaining tabs lock the card securely in place during wear. Features Dual Attachment Points: Lanyard and clip slots at both the top and bottom edges so you can hang it standard or tether it down. Snap-In Tabs: Low-profile overhanging clips securely grip the top and bottom of the card. Thumb Ejector: A large central window in the backplate makes removing the badge quick and frictionless.
Dog Remote Belt Holster 3
Fumbling for the remote when you actually need it defeats the point of having one. This holster locks the transmitter to your belt so it stays exactly where your hand expects it to be. The front channel leaves the main buttons clear to press without drawing the remote, and the bottom cutout lets you push it up easily when you do need it. Fit Details Sleeve Dimensions: Fits bodies up to 34 mm wide and 28 mm thick. Clip Capacity: Fits belts up to 45 mm (1.75 inches) wide and 6 mm thick. Printing: Print standing upright. PETG is strongly recommended over PLA so the belt clip has enough flex to snap over your belt without snapping off.
Embossed Corporate Logo Keychain
A minimalist, single-piece keychain blank featuring raised corporate typography. The body uses a flat-bottomed pill geometry to print seamlessly on an FDM bed without supports, while the integrated mounting hole ensures the outer perimeter remains completely uninterrupted. Print Specifications: Dimensions: 65 mm × 32 mm × 4.2 mm (total height including text). Mounting interface: 5.5 mm diameter integrated hole, positioned for 4 mm of solid wall thickness to resist torsion. Lettering clearance: Text is extruded 1.2 mm above the base layer, providing enough depth for a mid-print filament swap if high-contrast text is desired. Material guidance: Prints cleanly in PETG or PLA. No brim required.

Piaggio Yamaha Demon Keychain
A solid-block Piaggio and Yamaha crossover keychain. The tuning fork emblem takes the center, flanked by sunken demon faces tucked neatly inside the primary shield perimeter. Overall footprint: Scales out to 40mm wide by 60mm tall. Key ring bore: Roughly 4.4mm internal diameter on the revised scale. Fitment note: Verify your split-ring gauge against the bore before committing to the plate. Prints dead flat.
Wishbone Pendant with Windblown Ribbon
What it's for A classic organic wishbone pendant featuring an integrated chain loop and a dramatic, windblown ribbon tied at the neck. Designed with an entirely flat back so it drops straight onto the build plate, it captures a specific aesthetic silhouette in a ready-to-print form. Dimensions The pendant measures roughly 58 mm wide by 67 mm tall, giving it a bold presence that works well on a longer chain or cord. Print notes Since the back sits flush at Z=0, no supports are required. Print it flat. A smaller nozzle or lower layer height will help capture the dome of the bone and the taper of the ribbon tails perfectly.
Creality 8-Key Switch Tester Set
An 8-slot mechanical switch tester keychain featuring a rigid frame with standard 14mm square cutouts for mechanical switches. Now includes eight matching keycaps forming the word "creality". Frame: 175mm wide frame with side-engraved "creality" text and a 5.5mm keychain loop. Keycaps: 8 individual keycaps with Cherry MX-compatible cross stems. Assembly: Snap your own switches into the frame slots, then press the printed keycaps onto the stems.
Flush Face Bean Fidget
What it's for A pocket-sized fidget shaped like a standing bean, designed to house a standard Cherry MX mechanical keyboard switch. The face plate acts as an oversized keycap, sitting flush within the body's front pocket when at rest, and depressing smoothly inward when clicked. Dimensions Overall Assembled Size: ~36 x 24 x 50 mm Switch Fit: Standard 14.1 mm friction-fit MX socket with bottom clearance for the center pin. Face Cap Tolerance: 1 mm gap around the perimeter of the face plate to ensure frictionless travel inside the pocket. Assembly Snap an MX switch into the back of the body cavity. Press the face plate's rear stem bracket firmly onto the switch's cross stem. No glue required if tolerances are dialled in on your printer.
Montana keychain
A 50×20mm solid fob block featuring a standard 4.5mm through-bore on the left flank, properly sized to clear 4mm jump rings or standard split rings without binding. Clearances: The bore is positioned to leave exactly 4.75mm of solid wall at the left edge. Chassis: Base deck sits at exactly 3.0mm thick, laying completely flat on the build plate. Emblem: A classic bowtie geometric profile raised 0.8mm above the base, bringing overall thickness to 3.8mm. Fits standard key rings, though heavy-duty 5mm carabiner hooks will not clear the bore.
M22 Threaded Kettlebell Stash
A two-piece threaded kettlebell stash keychain. The main body has been hollowed out to maximize internal storage, then split squarely at the equator with a sturdy 2mm-pitch thread holding the halves together. Both halves print exactly as oriented — the base sits flat on its machined underside, and the top half prints directly on its equator ring. Fitment Notes Thread Clearance: Engineered with a 0.5mm radial offset on the internal thread. Check your flow rate if the halves bind on the first turn. Split Ring: The arch remains standardized for a 1.5mm wire gauge ring. Internal Volume: The cavity is approximately 20mm wide and 19mm deep when closed. Fits standard folded emergency bills or small hardware.
Zahra -girl
A freestanding, bold typographic nameplate cut in Archivo Black. Set flush to the build plate at a clean 2 mm thickness, this design drops the traditional backplate entirely for a minimalist, letter-only look. Print notes Pieces: Prints as separate letters (no overlapping or connecting structures) Thickness: 2.0 mm flat extrusion Build Plate Adhesion: High surface area allows for easy bed adhesion without brims
Football Keycap Topper
A custom Cherry MX-compatible mechanical keycap featuring a gently domed top and recessed seams, channeling the look of a classic basketball. Built from the ground up to respect a precise 17.25mm footprint, it trades the standard typing dish for a smooth, tactile convex surface. Court-Ready Specs Switch Profile: Deep Cherry MX compatible stem with a flared entrance for an easy press-fit. Surface Feel: A smooth domed top intersected by 0.6mm-deep recessed channels tracing the iconic hoops cross-and-arc pattern. Dimensions: Exact 17.246 mm square footprint at the base, tapering cleanly up to the rim. Printability: Designed fully manifold with built-in internal bracing ribs. The bottom cross interface is lightly chamfered to combat elephant's foot and ensure tight tolerances straight off the bed.
CourtGuard — Vented Finger Splints
Designed to quickly immobilise jammed or sprained fingers, CourtGuard splints provide rigid support without trapping moisture. Ideal for handling the inevitable basketball court impacts, the half-cylinder trough design features a rounded capsule geometry that sits comfortably against the skin without digging in. A dorsal ridge of vent holes keeps the finger cool during recovery, while integrated side notches securely anchor standard Velcro straps to keep the splint exactly where it belongs. Sizes Included Small (Pinky): 55mm length, 15mm inner diameter, 4 vent holes. Medium: 65mm length, 18mm inner diameter, 5 vent holes. Large: 75mm length, 21mm inner diameter, 6 vent holes. Print Notes All three sizes are designed to print-in-place in their current flat orientation, requiring absolutely no supports. A rigid material like PETG or standard PLA is recommended for maximum immobilization.
Horizontal Fidget Tower
hi
19.6mm Peg Fidget Base
Stripped-down version of the 70% scale mini fidget, retaining only the primary 48mm base and the 8mm rattle beads. All slider, cap, and collar mechanics have been deleted from the layout. Fitment and Clearances Base Peg: Measures exactly 19.6mm in diameter after the 70% scale factor is applied. Beads: Scale down to 5.6mm diameter. Compatibility: Does not include the upper chamber; the beads are supplied loose and will not be contained unless mated to a custom upper receiver.
AetherAssist — Cyberpunk Watch Prop
A chunky, futuristic wearable casing inspired by dystopian gear. Designed as a solid dummy prop for cosplay or display, it features an angular geometry, heavy chamfers, and an oversized aesthetic. Features Rugged Profile: 46x56mm footprint with a 12mm thickness. Strap Lugs: Integrated 24mm strap gaps with 2.5mm pin holes ready for standard watch hardware or paracord. Control Array: Features a hex-machined primary dial and a secondary rectangular action button on the right flank. Print notes Prints flat on its back. The strap pin holes bridge easily, but verify your printer's overhang limits for the recessed strap gaps.
