M6 tap hole T-nut for 30x30 or 40x40 slotted extusions

I remixed this nut in order to only have a 5.0mm DIA hole which is then tapped to M6 thread to have a 100% plastic part.

If you already have a tap kit available, and don't want any steel in your part, this could be a better option than press-fitting a nut.

Printed in PETG with 4 perimeters and 25% infill worked very well; didn't try with other materials.
