The T-Slot nut is suitable for rails 30x30 and a width of 8mm.

To ensure T-Slot nut is fixed also in vertical position, I have designed a TPU spring which is fixed to main body by a dovetail groove.

I recommend to use a TPU with a low shore hardness. For my part I have used colorfabb varioshore with a setting to get a shore hardness below 85A. After printing, add a nut M4 to the printed part.

To assign the different materials to the T-Slot nut, you have to split the .stl into parts in your slicer.

Due to the dovetail groove, the T-Slot nut is printed on a Prusa-XL. I guess with an MMU it will also work.
