Dust port adapter

thingiverse

I made a part for a friend after his dust extractor died, so he could try running an industrial sand off a shop vac in a pinch - not the best solution, but a 5-hour print meant a quick fix for an immediate problem. The top inner dimension is 35mm and the larger bottom dimension is 102.5mm. I added extra fins to the exterior to reinforce layer lines and reduce the risk of the part cracking open along those lines under side-to-side loadings from shop vac hose removal and installation.
