OpenBuilds Inside Hidden Corner Bracket with Threads for V Slot extrusion

I modified OpenBuilds' inside corner bracket to include 5mm threads, which allows the set screws to be placed more easily.

Print with 100% infill at .12mm or finer layer height with a .4mm or finer nozzle.

Use supports and the orientation shown in the picture, no support is needed for the threads.

You'll need some set screws, which you can buy here: http://openbuilds
