RC wheels always crack at the hub after a bad jump, or spin out when the stock treads wear flat. This is the right-side replacement—built dense enough to survive a hit, with directional treads angled specifically for the starboard side to keep it digging into the dirt instead of skating over it. Fitment Details Dimensions: 65 mm outer diameter, 18 mm width. Axle: 5.2 mm central bore (fits standard 5 mm RC axles with clearance). Print Settings: Lay it flat. No supports needed. Run it solid or with dense gyroid infill to keep the hub from tearing out under torque.

Material: Designed for rigid filaments like PLA or PETG.
8-Camion
A truck missing one wheel is just a seesaw that scratches the floorboards. Stripped hex hubs or worn treads usually end a run early; this is the right-side replacement to get it rolling flat again. The tread channels are cut at a 20-degree angle to specifically mirror the left side, keeping the traction profile symmetrical. Fitment and Print Details Outer Diameter: 78 mm Width: 26 mm Drive Interface: Standard 12 mm RC hex socket (6 mm deep) Axle Clearance: 5.2 mm bore, clearing standard 5 mm axles. Printing: Drop it flat on the inner face (the hex side). No supports needed; the outer rim inset chamfers cleanly. Needs dense infill around the hub to prevent the hex from rounding out under torque.
7-Camion
This is a rugged, heavy-duty truck wheel designed to anchor the front-left corner of a modular exhibition chassis. Coming in at 78mm in diameter, it features a deep-dish rim, aggressive sidewall tread cuts, and a prominent central hub studded with hex lug nuts. Fabrication Notes Print Orientation: Flat on its back face. Overhangs: Sloped internal cavities mean it requires absolutely zero supports.
