Fully printed spool holder.
A fairly straightforward spool holder, designed for 52mm centre spools, made using Emmett's gear bearing http://www.thingiverse.com/thing:53451
Desined to fit Kossel Mini 3d printers with a side length of 240mm.
Inspired by the work done on this: http://www.thingiverse.com/thing:392948
Updated the SCAD file for the bearing so that the flange resizes correctly.
As a minimum yiouwill need to print:
- 1 x bearing.stl
- 1 x groupset.stl
I printed mine using 0.2mm layer height and 0.4mm nozzel.
The code for the gear bearing has been modified to add the flange at the bottom so as to support the spool. I have also increased the tolerance to 0.3mm to make it easier to print on my then uncalibrated printer. You may be able to reduce this back to 0.15mm if your printer is well dialed-in.
The hole in the middle of the bearing has been sized to take a standard brass PCB standoff, but you could simply use a nut and bolt, juse set the width of the centre hole accordingly in the SCAD file.
All the parts for the bracket can be printed together by downloading the groupset stl file. If printing seperatly you will need to print three brackets, one centre plate and one bearing.
