Sander Vacuum hose adaptor

thingiverse

I whipped this up quickly when I needed to sand the boat and didn't have the correct adapter for my shop vac. The diameter of the sander side is just right, but very snug; the diameter for the shop vac side is also perfect, except it's designed specifically for a Ryobi, so your mileage may vary. The CAD file is included, in case you want to make any adjustments. It wasn't rocket science, but it got the job done.
