filament spool holder
thingiverse
A spool holder for 1.75 1kg spools. What I did was measure the spool holder that came with my anet printer and through tinker cad I duplicated as much of it as I needed then I made a center spool roller that will fit the filament and the holder it uses 2 M5 screws in each end of the roller to mount the filament to the holder the holes are 4.5 mm so a m5 screw will thread into it leave enough sticking out to allow the head of the screw to slide over the slot end to keep the spool from moving side to side no support is needed as I made a way to reduce filament use and still not need support.
