MINI-z-bottom R8 with Fysetc/uxcell T-Nuts

Fysetc 3030 series slide-in t-nuts with M3 threads (also commonly available on Amazon under uxcell brand) are slightly larger than the spec nuts for the Mini+. 

I remixed the MINI-z-bottom part to have a larger gap between the extrusion alignment protrusion as shown in the attached pictures in order to support the larger Fysetc/uxcell nuts. 

I used this modified part successfully while building a highly customized Mini+ and it worked without any problems.

The source files are attached, please modify yourself if your tolerances/t-nuts require it. 

Cheers!
