Quick Change Spool Holder, Mostly Printable w/ Preload bearings

thingiverse

I wasn't satisfied with the printable spool holders I was finding on Thingiverse, so I made my own to fit my needs and space. It features a hub mount on ball bearings with an adjustable preload, and a quick change mount. The non-printable parts are minimal, and it doesn't need any added supports. The longest part only measures 92.5mm, making it printable on any size printer. I've included a wall mount version, as well as both 1" and 2020 aluminium extrusion mount versions. It currently fits a 1kg Makergeeks 210x75mm spool with a 51mm hub bore, offset 19mm on one side. More sizes are coming soon. Printed parts include: * 2 Hub_v2 * 1 Hub_Tube * 1 Outer_Hub * 1 Outer_Hub_Long * 2 Arms of choice, with one mirrored Required hardware includes: * 4 606zz bearings * 2 M6x30mm hex head bolts * 4 M6 nuts * 4 M4x10 screws * some M6 washers Cad files are available at http://a360.co/2mSrPex. Print settings used include: * Printer: i3 * Rafts: No * Supports: No * Resolution: .2 * Infill: 35% - 50% Notes: The outer hubs have a support bridge in the hex, so no added supports are needed.
