RC Car Bevel Gear Rear Drive
A rear-axle drive for an RC car where the motor shaft has to turn 90° into a cross-car axle without the gears skipping or the motor shifting. This set uses a 12-tooth pinion and 24-tooth crown gear (2:1) on a 103.9 mm × 6 mm axle, with an open motor cradle instead of a closed box. Key numbers Gears: module 1.5, 20° pressure angle, 4 mm face width, 90° shaft angle Pitch cone angles: 26.57° (pinion) and 63.43° (crown); cone distance about 20.1 mm Pinion bore 2.1 mm, crown bore 6.2 mm, both with M3 set-screw holes in the hubs Axle supports: 6.4 mm through-hole plus a 17.3 mm seat for 606 bearings (6×17×6) Base: 84 × 92 × 5 mm, M3 holes (3.4 mm clearance); cradle slots allow forward and back adjustment Motor cradle parameters at the top of the file: mw, mh, wall, saddlel, saddley. Measure the real motor and edit them Cover is open at the bottom, with two M3 ears at the rear Printing Print gears with the hub facing up or down on the bed; PETG or nylon preferred Cover prints open-side up without supports Axle is a separate 6 mm steel rod; M3 screws hold supports, cradle, straps and cover
25mm Tactical Tabletop Tokens
A complete set of nine 25mm wargaming tokens tailored for tabletop tracking. Designed with a clear separation between the base and the raised lettering, making them perfectly suited for a mid-print filament swap or a multi-material system. Specifications Dimensions: 25 mm diameter, 4 mm overall height. Tolerances: The raised text and outer rim sit exactly 1 mm above the base layer, creating a clean Z-height transition for color changes. Printability: No supports required. The bottom edges feature a 1 mm chamfer to prevent elephant-foot distortion on the first layer, ensuring the tokens remain perfectly circular and easy to pick up from flat tables. Layout: Arranged in a flat 3x3 grid for immediate batch printing. Can be split into individual models in the slicer if needed.
Saipa Pride 111 Clock Bezel Phone Cradle
Preliminary replacement for the Saipa Pride 111 (2011 / 1390) dashboard clock bezel, with a landscape cradle for the Samsung Galaxy A54 5G. All bezel dimensions are placeholders and not taken from the car. Fit status Host: Saipa Pride 111 clock opening. Bezel size, spigot depth and clip positions are placeholders. Phone: Galaxy A54 5G, 158.2 × 76.7 × 8.2 mm, plus 3 mm case allowance and 1 mm clearance per side. Does not fit other Pride trims or other phones. Measure before printing Dash opening width, height, depth, corner radius and clip or screw positions. Notes The cradle is wider than the clock opening, so it projects forward of the dash. Open-top slide-in loading, side lips, a bottom ledge and a USB-C side slot. Tilt is 15° back. Check it against the dash and your sight line. Print in ASA or PC-CF. PETG softens in a hot parked car.
Domed Wickiup Terrain Shelter
A hollow dome structure designed to represent a wickiup or wigwam shelter. Useful as tabletop terrain or a diorama element. Overall Size: 100 mm diameter footprint Structure: 3 mm wall thickness Features: Domed exterior, arched front entryway, and a central top vent hole Base: Sits flat on the build plate for easy printing
OO Gauge semi detached house central doors and sloped chimneys
A semi-detached pair built from two 72 mm small-house frontages, 144 mm wide overall and 72 mm high, in OO-gauge style. Each half has a central door, a small window either side and three windows above, all in Flemish bond brickwork. Quoins appear only at the two outer ends of the pair. One roof piece covers both houses, and two single chimney stacks print separately. Remix hooks Frontage width: each house is 72 mm. Changing it rescales the wall, trim, roof (frontage plus 8 mm overhang, currently 152 × 25 mm) and floor (138 × 15 mm). Chimneys: 9 × 9 mm stacks, 20 mm tall with a 11 mm cap. Taller or wider stacks, or a stack pair with more pots, are easy variants. Mirrored halves: both doors are centred, so a handed pair with doors at the party wall is a simple swap of the opening offsets. Inserts: ten windows (12 × 16 mm) and two doors (12 × 28 mm) print separately at 3 mm thick. Openings are 0.4 mm oversize. Pairs with: a party wall between the houses, or longer side walls for a deeper roof.
