Description
Wanted to make an adapter to work with the included parts, this can be installed on your already assembled INDX.
This thing attaches to your filament sensor assembly and allows you to connect PC4-M10 passthrough fittings, or another model for ECAS04 fittings (Remove the rubber part)
Use 2 M3 x 18mm Socket Head screws to attach using the same screw hole that secures the filament sensor PCB.
There are two versions for ECAS, I had some plastic ECAS and Metal ECAS on hand and they were different sizes for whatever reason. Your ECAS might be a different size than the two I have, so be aware of that.
These are the ones that I ordered and arrived in Metal, even though the photo on Amazon clearly shows plastic ones, https://www.amazon.com/dp/B099NPWSFB
Print without supports, print as the model loads in your slicer.
This is a spiritual successor to one of my original mods of the MMU2, in 2018, we sure have come a long way since then!
Update: I added a "V2" version, it is just a cosmetic difference, so you have a choice on which one you prefer. It adds back some aesthetic features from the Prusa design (although slightly different).
