Wall Mounted Bracket - 6MM Slot

I needed a strong wall bracket to mount my XCarve electronics, which had a slot for a 5-6mm perspex sheet.

I designed the following to be printed in two halves and when bolted together makes a really strong but light right-angled bracket.

If you need a different sized gap (+- 1-3mm
