SUNLU Dryer S2 Mod

This improved version is designed to prevent the filament from falling off the roller when the filament material is exhausted and to roll well without resistance.

Some parts of Multiple Mechanism Auto-Rewind Spool Holder have been modified, and parts other than the modified parts must be found and downloaded from the original model. 

due to the small width of Sunlu Dryer, we cannot accommodate all filament spool sizes.

The video below shows how well the filament rolls

I have updated additional bolts and nuts in the link below. It might be better to print this out too.
