Prusa i3 Spool Holder

This is my custom made spool holder for Prusa i3. It fits the 6mm aluminium frame I had.

The spool holder can be placed to face forward or backward enabling to install the filament to the direct drive extruder with or without PTFE tube.

I have put 2 different size of the length. The shorter one fits the 3DP spool, while the longer one fits almost any spool.

The extruder I used in the picture is direct drive extruder designed by ffleurey:
