I have a Qiditech Dual Extruder, the filament loaders that came with the printer were ok for the initial filaments I purchased, the spooler length is 69mm in length.

I recently purchased more filaments and all of these are 1kg and require a longer spooler length as the width of each of these filament reals is closer to 79mm in length.

I tried printing a spooler from ThingiVerse, but the thread was wouldn’t screw into the printer. Is there a spooler loader that is compatible with the Qiditech printer and will work for the measurement’s in this post?
