USB Power Adaptor Box

Case to hold two USB power buck converters. Allows use of old 12v and 24v power supplies (6v to 35v really) to create independent USB power adaptors with both B and C jacks.

For buck converters, see: https://a.co/d/fPRJsEN 

Note: a 12v supply (like an old obsolete EERO router supply) allows 9v USB power. A 24v supply would be better and allow higher voltage. Buck converter claims 60watt max, supports PD 3.0.

CAD file is parametric so you can modify to hold more than two buck converter modules.
