I couldn't find an existing model of a spool holder that I like so I designed my own.

Many stick the spool on the side of the machine but I wasn't a fan of the 90degree turn the filament had to make before entering the ptfe tube.

This design keeps the spool inline with the machines ptfe tube.

The bracket mounts to the back of the machine using existing M3 screws.

For the spool shaft I used:

• 2x 608 bearings
• 4x m8 nuts
• 2x m8 washers
• ~120mm length of m8 threaded rod.

I have included a sectional view so you can see how the spool shaft is assembled.

This may also work for the X1C but I cannot confirm (as I don't own one).

Printed in Polyterra black PLA, 3 walls, 20%infil and seems to be holding up fine so far.

I'm interested to see what improvements / modifications others make to this design.
