Ultimaker Filament Reel Holder

thingiverse

This printable alternative fits reels with smaller hole diameters, such as those from my PLA batches (37mm diameter). It works for reels up to 6.5cm wide and can be lengthened via OpenSCAD for wider reels. Version 2 has a wider gap for Ultimaker compatibility. To install, print two arms, one holder, and one end; place arms on bracket, holder on arms, reel on holder, and end piece in notches at arm ends. Confirm successful printing to keep V2 or remove old version.
