Low profile spool holder

I set of to make a universal wallmounted spoolholder (so that I can have my UM2 closer to the wall) Had to be able to handle any size of spools.. I mainly use ø200 up to ø310mm spools.In adittion to the 4 printable parts , you will need: 5 pcs of 6*9*6mm bearingsM6 nuts and screwswall mountink screws of your picking.Have fun.STL's are of my simpler design…..maybe better to print and less material
