Description
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.

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.
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.
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.
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.
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.
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.
