I've been using an adjustable width spool roller for quite some time now, but it's annoying when you change rolls a lot, if they are different in width.So i decided to make a roller that could fit most spools.Updates:V2 - 24 April 2021 Generally beefed up entire designRemoved tapered angle on rollersAdded lip on roller edge to avoid roll ‘walking’ into the space between roller and side. BOM2x Side_Panel.stl2x Joiner.stl4x Roller.stl4x 608ZZ Bearings (or other matching bearing)2x 162mm metal rod that fits inside your bearings (i used M8 threaded rod, 5/16th threaded rod should also work)Print InstructionsEverything was printed using the default "0.35mm Fast" profile in PrusaSlicer, with following changes:5% Rectilinear Infill3 PerimetersAssembly InstructionsStart by laying down both side panel prints and add bearings, they should be a tight press-fit.Put one side panel aside for later, and add metal rods to the other.Add 2 rollers to each metal rod, make sure that the flange is pointing outwards towards the bearings.Insert the 2 Joiner's to the side panel, should be a snug fit, and should not fall out by it self (if its too loose, consider a drop of glue).Add the last side panel you put aside, and put it on top, and then press the Joiner's into the side panel to secure the whole assembly.Finished!
