HSW Ball bearing filament spool holder

Overview

Modified Ken226's great spool holder that I really like so it works on the side of my Voron 2.4 300 that has HSW mounted to it.

I'm space constrained on the side, so I needed something where I can put spools in from the front.  Figured two of these rollers would work well under a spool.  Of course, you could use it “normally” also, with the roller through the spool hole.  

I like that this keeps the spool back a bit from the front door (I have clicky-clacky) and allows some freedom for where to put your spools. 

This is in preparation for my Stealthchanger setup where I will have two spools mounted on each side.

BOM

For each roller:

• (2) 6082rs or 608zz bearings
• (1) M3x8 to mount endcap to body
• (1) M3 heatset insert
• (2) M3x8 to mount endcap to HSW inserts
• (2) M3 nuts for HSW inserts

Printing

I printed with standard Voron specs.  Should work in PLA or PETG or ABS/ASA

No supports needed!  The original design has a nice built-in support for the center peg.

CAD

Original (messy) files available from Onshape.  

• Combined various files
• Added “double” endcap for better strength when using two rollers under filament spools
• Modified bracket to be stronger
