Multiboard Corners 45° & 90°, 6.25, 8, 12.5 & 15mm

I have an insider corner above my workbench where I am putting up a multiboard. I couldn't make any of the premade brackets work for my needs, so I made my own. These are working for me and can be seen in the attached images

Added 6.25 mm versions for the 90s.

I had some people request a 45 degree version instead of the dual and quad corner connectors so I added those. 

Additionally, a corner corner connector was requested for the 90 degree. This effectively gives you a box connection. 

I want to always keep my designs free for anyone who wants to use them, but this does take time and effort. So if my designs are worth something to you, please feel free to buy me a beer
