Hello, 

This replacement cap has been designed for the Wolfcraft Precision Knife and is intended to be printed in TPU. Please use the recommended print/filament profile. You may need to adjust the nozzle temperature; my filament requires 240 degrees Celsius, while the Bambu filament works best at 220 degrees Celsius. Feel free to download the *.f3d file (Fusion 360) and modify the dimensions if the cap is too snug or loose.
