I needed a mounting bracket for a dry box I was making. I wanted to reuse a 3/4" dowel I already had lying about but I couldn't find a bracket that was quite what I needed.

The outside piece helps re-enforce, provide air blocking, and to provide shallow recess for the nuts to stop them turning during tightening.

Assembly:

• Hardware:
  • 8x M3 x 8 screws (4 per side)
  • 8x M3 hexagonal nuts
• I used a ruler to try to find the center of each side (you can see my sharpie mark). Then used the back pieces as a template to mark the holes I needed to drill through the storage box I was attaching them to.
