V-Slot Corner Bracket With Adjustable Foot

This is a rather over-engineered corner bracket for V-slot extrusions.  Features include:

• Alignment guides
• Captive T-nut slots for use with cheap “hammerhead” style nuts
• Adjustable height foot

Print with at least 3 perimeters and high infill, no supports.  Intended hardware is all M5.  Extrusion bolts are M5x10, button head, M5 washers recommended.  Foot bolts are M5x? whatever length you need.  The captive hex nut for the adjustable foot is a bit of a pain to install, the corner of the bolt goes into the slot.  I find it helpful to use two small flat-head screwdrivers to align it and get it started, then press it into place.  If you need to lock the foot into place more securely, you can add a washer and hex nut above and below the corner brace on the foot bolt, and tighten them into place once you have adjusted the height.
