Quick Swap Spool Holder with various Mounts by tinkerz

Last crawled date: 3 years, 1 month ago

Work In Progress - This is an early release to allow feedback.
Spool holder designed around an unreleased design for a universal core to the Spannerhands Enclosed Spool holder. The Spindle and Nuts hold the spool upright and centered while the caps on the bearings allow for a quick and easy swap of spools in and out of the spool holder uprights.
There are two different designs for the spindle portion.
A) Print 2 Bearing Caps and use 608 bearings for fast free rotation of spindle
B) Print 2 Printed Caps and the 8mm Replacement Rod for slower rotation with some drag/friction/pre-load
There are currently 5 Mount options:
a) 40mm Extrusion (like on the Formbot T-Rex 2+)
uses an M4 hammer/T-nut and screw to secure to extrusion
b) 30mm Extrusion
uses an M4 hammer/T-nut and screw to secure to extrusion
c) 20mm Extrusion (like on the Ender 3)
uses an M4 hammer/T-nut and screw to secure to extrusion
d) Prusa i3 MK2/MK3 frame mount
uses a trapped M4 nut and screw to tighten to frame
e) Zortrax frame mount
[intended to rest on top of 3.5mm (or less) of overhanging metal]
uses a trapped M4 nut and screw to tighten to frame
