Joins two MicroRAX or Mini-T 10mm profiles at a corner. Extra hole for diagonal, rubber foot or other accessory.
Use .080" - .130" aluminum for best results. Laser cut plastics are good and light weight.
Holes are sized to clear an M3 screw. Use a washer or shrink the holes to clear an M2 screw for Mini-T profile.
The tools listed are a range of tools that can be used to make the part, you won't need all of them.
A MakerBot, of course, will be the funnest way to make one.
Let me know if there are any file types that would help and I can add them. One of the few I can\'t create at the moment is Google sketch up.
Note: The DXF file looks blank but the geometry is there, I downloaded and checked it.
