Sunlu S1 Filament Rewinder/ ESpooler N20

This is still a work in progress but i think it's ready to test print? I have included only the fusion360 and step files so far as im yet to print and test any stl files 😅. il be updated and adding the stl files as I test. any feedback would be a great help 👍.

update: I tried the manual version with my ercf v2 and it has to much friction to work reliably but could work well with other mmu that have proper extruders or by redesigning the tension arm to reduce the filament angle. After noticing the brilliant happyhare software which i use for my ercf v2 now supports “espoolers”. I decided to give that a try using a spare n20 motor i had lying around. I will be testing shortly and have shared the files here if you would like to test it. 

update 2: ive test printed the N20 version using petg and it all fits together nicely and works great.

update 3: the 3d printed n20 shaft started to wear causing the one way bearing to slip sometimes so ive add a metal sleeved version to stop the wear. it uses 8mm x1mm wall thickness round bar as the sleeve.

update 4: added a  38 tooth gear without the one-way bearing to allow the motor to move the spool forward during a print or loading and removed some old files to clean things up abit.
