This is a 1/10 scale model wheel, 2 inch diameter, intended for 3d printing using a flexible material like nylon or PETG. Very rugged, designed for high impact robotic applications. Tweaked design for maximum strength with Solidworks Simulation.
Designed with Solidworks. I did a test print with PLA on Anycubic Kossel Delta printer modified with Trinamic 2100 stepper drivers and V6 hotend.
