Pursa Mini/Prusa Mini+ T-nut for extrusions (M3 nut insertion)

I made this remix of the design made by HD_Creator (https://www.prusaprinters.org/prints/42971-t-nut-for-pursa-mini-extrusions-groove-8-type-b-m4/comments) because it feels safer to screw against a metal nut instead of the plastic. Also I use M3 mostly and I have a collection so hence the design.

The nut fits really snugly so press it to insert it. This way it will not fall off inside the extrusion.
