Print-in-Place Tri-Wheel Fidget
Created today
Description
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.

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.
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.
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.
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.
