Quick Change Spool Holder, Mostly Printable w/ Preload bearings

cults3d

I wasn't satisfied with the the printable spool holders I was finding on Thingiverse. They were ether outside roller types or were long rod types, Nether quite fit my needs or space. So I made my own. It features hub mount on ball bearings with an adjustable preload, and quick change mount. The non-printable parts are minimal, and it needs no added supports. The longest part only measures 92.5mm, so it should be printable on any size printer. I have included a wall mount version, and both 1" and 2020 aluminium extrusion mount versions. It currently only fits a 1kg Makergeeks 210x75mm spool with a 51mm hub bore, offset 19mm on one side. More sizes to come.
