ZYLtech Texas spool holder. 5KG Spool!

thingiverse

This spool holder will hold up to a 168mm wide spool. It uses 4 608 skateboard bearings with a low tolerance/loose fit on the actual rollers but it fits tight with a small bit of force required to slot them in. If you have strength issues on the rollers, it has an m4 holes through each end but its not required. NOTE - If it is rubbing, be sure its centered. I forgot to make it so it locates in the center on its own, perhaps that will be fixed in an update . Also, as a recommendation, line up your Z seam so its easier to sand. if you dont want to line it up or sand it, check if your slicer to see if you can place it inside the model.
