This is an attachment for the original Prusa Mini spool holder which allows adding a PC4 M10 quick release adapter for a common PTFE tube. Primarily I use this for a reverse bowden setup on my MK3.

Printing:

• any solid filament
• 0.2mm layer height
• 0.4mm nozzle
• 15% infill
• 2+ perimeters
• no support when positioned on the left or right surface

Additional parts:

• 2x 10mm M3 screws for the regular version 1x 6-8mm M3 screw for the slim version
• 1x PC4 M10 PTFE fitting ( 0.9-1.0mm thread pitch )

Place between the spool holder's bases as shown in the pictures and don't overtighten the screws when you lock its position on the rail!

Update History:

• 22-07-04: Fixed the slim version's back chamfer
• 22-05-23: Added pictures of the slim version test print
• 22-05-18: Added a slim version in order to support small ≤ 500g spools ( e.g. 500g Basicfil )
