While cutting up vacuum extension wands for this is expedient, it’s a bit problematic given that Shop Vac recently filed for bankruptcy, was bought at the last minute, and production hasn’t caught up.
I need a receptacle for the Sweepy 2.0 dust fitting — one option would be to purchase one from Woodcraft, but Carbide 3D sells blocks of HDPE:
which looks to be just barely big enough for things to fit.
Measuring the hose fitting I get a diameter of ~63.5mm — offsetting that twice we arrive at:
which it is pretty straight-forward to render toolpaths for:
but this thickness stock raises the concern of rubbing and tool engagement, so we add some geometry to take this into account and rework the toolpaths to follow best practices.
