Articulated Sim Racing Keyboard Arm
Created 4 days ago
Description
This modular arm mounts a Logitech K235 wireless keyboard to a tubular sim racing chassis, allowing you to swing the keyboard into your lap for typing and fold it away while driving.
The mechanism relies on structural box-section arm segments and heavy-duty M6 bolted joints to prevent sagging and resist vibration. A split-clamp base mounts to the frame without drilling, and the central keyboard tray uses recessed neodymium magnets to keep the keyboard anchored during intense force-feedback moments.
Hardware Required
- Cockpit Mount: 2× M5x50mm bolts & hex nuts.
- Articulated Pivots: 3× M6x40mm bolts, washers, & nylon lock nuts.
- Keyboard Retention: 4× 10x3mm circular neodymium magnets (press-fit or glued into the tray).
Printing Advice
- Material: PETG, ABS, or ASA for rigidity and impact resistance.
- Orientation: Print all parts flat on the bed as laid out. The tray is designed compactly to fit comfortably on a 220x220mm print surface.
- Settings: Use a minimum of 4 perimeters/walls and 30%+ gyroid infill for the arm segments to ensure lateral strength.

Snap-Fit Poultry Band
A heavy-duty, flex-to-fit poultry leg band designed for easy application on turkeys. Customizing the Fit Band Diameter: Currently scaled for roughly a 1-inch (25.4mm) leg, making it suitable for mature turkeys. Band Width: The height along the leg is half an inch (12.7mm). The Hinge: The back of the ring thins out to 1mm to create a living hinge. You can thicken this if your material is exceptionally soft, or thin it further if you are using a stiffer PLA. The Lock: Features a horizontal bulb snap-fit. The locking pin squeezes through the entry gap and clicks into an enclosed cavity, keeping it secure even during movement. Adjust the bulb diameter or cavity clearance depending on your printer's tolerance.
Track-Ready Kart Frame
A half-meter-long go-kart frame complete with a full racing loadout. The chassis features lightweight cutouts along the floor pan and thick side pods for impact resistance, while the cockpit sports a contoured racing seat with aggressive side bolsters to keep the driver planted. Out back, a finned engine block feeds twin rear-facing exhaust pipes. Key Features Chassis Design: Extended floor pan with weight-reduction cutouts and integrated side pods. Racing Seat: Deeply contoured base and backrest with prominent side bolsters. Steering: Three-spoke wheel mounted on an angled column with a solid base support. Powerplant: Rear-mounted block engine featuring cooling fins and dual exhausts. Wheels: Rounded tires with defined center hubs mounted on robust solid axles.
Threaded Spoke Magnet Clamp
A zero-hardware, print-in-place clamp for mounting a 10x4mm cylindrical magnet to an e-bike spoke, designed for velocity sensors. The two-piece assembly uses an M16x2 thread to clamp directly over the spoke, trapping the magnet inside the cap and requiring no glue or screws. Magnet Pocket: Sized at 10.1mm to 10.6mm taper to account for ASA shrinkage, with a direct drop-in channel. Spoke Clearance: The slot accommodates standard bicycle spokes, self-centering as the cap is tightened. Standoff: The cap body is exactly 15mm long to position the sensor face properly. Material: Designed for ASA or PETG for outdoor UV and temperature resistance. No supports needed.
Red Planet Rover Chassis
A fully articulated, print-in-place scale model capturing the iconic six-wheel stance of off-world explorers. The design relies on the famous rocker-bogie suspension geometry, allowing the wheels to ride over uneven terrain while keeping the main chassis relatively stable. It prints entirely assembled as a single piece. Print Guidelines Clearance: Designed with 0.4mm gaps on all articulating joints. Orientation: Prints directly on its wheels. Support: No supports required. The internal axle caps are conical to bridge cleanly. Post-Processing: Gently work each wheel and pivot arm free after taking it off the bed to break away any tiny stringing inside the joints.

0.355 to 0.370 Golf Ferrule
Custom transition ferrule designed to mate golf shafts with an adapting taper. Before printing, verify your shaft tip standard. This part spans from a 0.355-inch taper dimension to a 0.370-inch parallel dimension. Critical Measurements: Inner Bore (Bottom): 9.0 mm (0.355") Inner Bore (Top): 9.4 mm (0.370") Outer Diameter: 13.5 mm (0.530") constant Length: 22.0 mm (0.875") Does not fit standard parallel-only 0.370" shafts at the base without binding.
