About this 3D model
Sunlu S1 Filament Dryer PTFE-Tube with Clip for inside for the Sunlu S2 in my Uploads look PTFE Tube for Filament, which can move in all directions. Adapter takes a 4x2 mm PTFE hose. This is pushed about 5cm inwards and about 10 cm remain outside (but can be changed at will, shorter or longer). see pictures Installation : remove the small PTFE piece and then you can insert the tube with PTFE. It also doesn't matter whether the filament is pushed through the PTFE tube from the top or the bottom of the roll. Both work very well. The last picture shows both Sunlu's S1 and S2 filament dryers. created in Fusion 360
