Bosch 3107DVS dust port to 2 1/2" hose end

thingiverse

I wanted to hookup a 2 1/2" shop vac hose end (OD of coupler ~58-59mm) to a Bosch 3107DVS. An old random orbital sander with a 5" pad. Weird Bosch port. Tough location. Works a treat though. The hooks will require M3 hardware. 2x M3 x 12mm 2x M3 nylock that are 5.6mm across the flats. Fairly overbuilt. 5mm walls pretty much all the way around. Did that since the hose itself is kinda heavy and the 2 1/2" port is cantilevered way out. I may update the design to make use of the small sliding support arm the sander comes with to hold canisters, but that arm looks rather wimpy.
