Here's a weird hanger I whipped up in Fusion360 to hold my small shop vacuum off of. I consider it ugly as sin, but whatever, it works.

There are two variants:

• The original, with 25mm wide hanger hooks
• The revision with a 55mm wide bottom hanger

Be sure to use thick walls with a lot of infill as I had one of these snap in half after about 2 years of it being just fine.

PS - I imported this from its original home over on Thingiverse.
