Description
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.

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.
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.
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.
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.
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.
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.
