Description

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 )
