I3 Belt tensioner for 623 bearings

This belt tensioner is designed to use 2 X 623 bearings, and fit in 10 X 16 slots. I made this as I had 623's laying around, and wanted to use them because their O/D of 10mm matches the 2.5 mm belt pulleys I have, creating a parallel belt path.

I appreciate others will have different slots and bearings so source included.

On the aesthetics, usual to form I and chamfered where practicable to give the final object smooth edges.

Thanks for looking and hope this helps someone out.
