About this model
Filament load/unload issues? MMU2 taking too much space? Not with this Auto-Rewind spool holder! It keeps filament on the spool during unloading, up to two full revolutions. The secret is a spring element which keeps some amount of rotational tension on the spool hub while unwinding. The weight of the spool plus friction of the surfaces define the slipping point; nearly-empty spools will rewind less but that is no problem thanks to the high ridges of the (empty) spool. Hub_Standard is suitable for standard 750g spools, Hub_Wide is used for the wider 1kg spools. Two bearings are needed, type 608ZZ with outer diameter 22 mm, inner diameter 8 mm and thickness 7 mm. These are the dimensions of the MMU bearings as supplied by Prusa. If you have different bearings or spools with a different cent…
