Filamentrollenhalter/Filament spool holder

Geeetech ABS, works a bit too good (broken in bearings from my hockey skates were probably. overkill) and I had to clamp the variable spool axis a bit so extruder does not overrotate the spool. Printed about 4kg across two 2,5kg spools, works great!

Frage. Welche Schrauben wurden denn benutzt? M3 und Gewindeeinsätze?

Danke ;)
