This mold pours a 22mm silicone wheel sized for the antweight (150g) combat robot class. Every wall carries a slight draft angle so the cured wheel pops free clean, and anchor holes molded into the hub insert lock the silicone to your hub instead of letting it spin loose under impact.
Run a lower Shore hardness silicone, around 15A, for a soft, high-grip wheel built for the traction a battlebox floor demands. Scale the mold up in your slicer for a bigger wheel and the same design principles hold: keep the draft angle, keep the anchor holes, adjust your pour volume to match. That makes this file a solid starting point for beetleweight and larger combat classes too.
