Spool holder design is excellent!

Its a very not good system for rewind the filament, dont print that !!!
@Childee_1162397 What was your problem? I use the winder several times a week and it works fine. I've tried different rewinders, but finally I modelled this simple one.
@JardaK66 If you have tried a better rewinder, please post a link here where it can be downloaded. Thank you.
What kind of bolts, sizes etc are needed for this ?
@JohnnyColor_438756 I added the fasteners to the model description
