Flashforge Finder Filament Rewinder

thingiverse

A print you can chuck in a drill to rewind filament onto the stock flashforge finder spool is really useful for keeping filament inside printer to avoid dust etc. Another person can use a dowel or something like it to hold the roll you are taking filament from. Later models will hopefully include handle to reduce stress on the drill side. Best printed horizontally to avoid the peg breaking off. Please note rewinding brittle filament from age or water will cause outer filament loops which are larger to be wrapped tighter and smaller and can make the filament crack. It's standard policy to have low humidity areas for 3d printing and this is another humidity side effect. New spools that haven't encountered moisture should be fine.
