Bản dẫn ống filament cho Creality Space Pi

This is a modification for the Creality Space Pi Filament dryer. I wanted it to be low profile and fit in the groove underneath. I also made it screw in so you don't need glue. It doesn't have large teeth on the screw because of design constraints. So don't wrench on it. When you screw in the PTFE fittings it’ll make it way more tight. Lastly I wanted to add the the ability to screw in fittings to make the PTFE tubes secure. The fittings will cut there own threads. It all has fairly tight tolerances because the parts are so small. I made a 2mm hole down the center of the screw. It was basically just a guide hole for a drill bit so you can have a more accurate hole. I included a step file just incase some one wants to adjust anthing.
