MUST be printed with FLEXIBLE filament so that it can conform to the rim.
A simple print to replace the tire scrap adapters that normally come with Thule straps.
Fits a standard 20mm wide Thule Tire Strap.
Tested with a 40mm and 35mm MTB rim. Should work with smaller/thinner rims depending on the filament used.
Designed for and printed with a 0.6mm nozzle, though other sizes should work fine.
