Update 02SEP26:
I've added a version with provision for ECAS fittings in the filament output holes, to replace the supplied collets.
Update 07JUL26:
I've added a version with provision for ECAS fittings in the filament input holes, so that PTFE tubes from, e.g. dry boxes, can be inserted. The top (outlet) holes are unchanged, and use the supplied collets.
NB. My model has assumed that the insertion holes for the supplied sleeves are redundant when ECAS fittings are used, so I have filled them. Since I have not yet received my Founders Edition kit this part is totally untested with the filament sensor parts (PCB, ball bearings, magnets etc). Feedback from those with the kits is greatly appreciated.
Description
Somebody had to do it :)
The filament sensor parts supplied with the Bondtech INDX upgrade kit have numbers printed on them so that you know which port corresponds to which tool. The 3D model of this part made available by Prusa when the kits started shipping doesn't have numbers. So this model simply remixes the original part to include port/tool numbers.
Print just the main part, so that the numbers are recessed, or print the numbers in a different colour. They are 0.4mm thick, and the numbers are face down on the build plate, so it only takes three colour swaps.
Parts for the left (ports 1-4) and right (5-8) are provided as STLs. I have also provided the OpenSCAD script that I used to make these parts, and it has options to change the font, font size, thickness, and even the digits. Since the script relies on Prusa's original part I have also included that.
The versions with the ECAS fitting holes have been designed with the standard printing orientation assumed (numbers on the build plate). Use the same numbers STLs as above to print the numbers in a different colour.
The ECAS fittings should be a tight fit but can be inserted by hand. The PTFE tubes will pass through the ECAS fittings and stop against an internal end stop.
