Server Rack Rack Stud

Ran out of rack nuts while building my MOD10 rack and didn't want to wait the 2 weeks to order off amazon to get more so designed my own rack studs. I add a arch ins the support between the studs to clear the support ribs on the MOD10 printed 10in rack but should work on any other 10 or 19in rack that uses square cutouts for rack nuts. 

Tuned the nut size to easily screw on after printing with my printer using a 0.5mm nozzle but the fit can be tuned by sizing up or down the scale of the but but leaving Z scale at 100%. I will be eventually adding rack studs spaced for 2U and single studs for other applications but in the mean time let me know if any adjustments or custom versions are needed and I'll do my best to get it updated.
