About this 3D model
New rims in the TWIN-MONOTUBE-PROJECT-AT20 style Best printed with high resolution or use my 3mf file optimized for Bambu X1C, as I have adjusted some settings. All surfaces should be ironed. I printed the base with 0.2mm and the upper areas with 0.08mm. Only 1 contour, as I found it looks better that way. The rim fits very tightly into my TPU printed tires, let me know if it should be too tight for yours. Ideally, it might even be best to print with a 0.2mm nozzle.
