M4 T-slot nut for Mendelmax

The design is the same as the original by blacky, i just redesigned in sketchup reducing the nut and washer hole and simplify the mesh for a better print.

My nut measures 8mm external diameter, and 3mm height. The washer is 9mm diameter and 1mm height.

I printed mine with PLA, .35 nozzle, .25 layer height and works good but if you want more strength reduce the layer h to .20. I sliced it with Slic3r
