Parameterized Corner Lead Nut Mount

I had the need to mount a lead nut in the corner of 2 - 20x40 aluminum extrusions and needed to be able to specify the center distance of the nut from the 2 walls. This SCAD drawing is fully parameterized and the included .stl is for a common nut with the center located 21mm from each wall.

Give it a try. You will need supports unless roll it over on one side or the other. Good Luck!

Update 12/7: Added v slot profile to the back sides for positioning. Can be turned on or off.
