Harbor Freight Chicago Electric Random Orbital Sander Dust Port

thingiverse

My Harbor Freight sander (Chicago Electric model 93431) just had a terrible little cloth baggie on a plastic clip-on frame for dust collection. It finally tore, but the motor seems fine and the velcro pad is still doing okay, so I made a little adapter to fit a Ridgid 1.25" dust collection nozzle onto it. I kept the original part that actually connects to the sander, and snipped it down so there's just under an inch of plastic for the adapter to fit onto. My particular 1-1/4" nozzle tapers from 30 to 32 mm outside diameter, so I just made the port 31mm. It's a tight fit on both sides, but the semi-circle went onto the remaining plastic of the clip quite securely (a heat gun or some dremel work may help), and the hose seems plenty snug enough for the moderate movement it will see connected to the sander. The design is quick and dirty, but I didn't see anything else online for this sander. I printed vertically, with the circular side down, and used supports.
