silicone wheel mold

# 3D Printable High-Traction Silicone Wheels (D-Shaft)
Upgrade your robot with professional-grade, high-grip wheels designed for N20 micro-gear motors. This re-engineered design eliminates the need for tiny screws or pausing prints to insert hardware—making it perfect for DIY builders and those who outsource their 3D prints.

Key Features
Hardware-Free: Precision 3mm D-bore for a secure press-fit directly onto the motor shaft.

High-Traction: 8-spoke "T-hook" geometry creates a permanent mechanical bond so the silicone tire never slips off the rim.

Efficient Mold: Includes a lid-free, dual-cavity mold design to minimize print time and material.

Lightweight: Optimized rim geometry (~9g) for agile robots like line-followers and micromice.
