Large filament spool coupler
Description
We ordered some large spool filaments (3kg) for the 3d printers in the shop. the spool dont fit on the spool holder that ultimaker come in with. We also have a 3/8'' steel rod that we put our filaments on, but the spool was too heavy to be pulled from. so I designed this spool coupler to reduce the resistance. v2 goes with the threaded axel v3 goes directly on the spool, axel is not needed the holder designed to fit on a luzbot taz6 frame( or other model with same extruded aluminum) work with 3/8" rod and 3/8''(0.375) ID, 7/8"(0.875) OD bearings *** apply some pressure evenly to press in the bearings feel free to message me if you need slight modification of the model!
