This is for a cheap-ass Horrible-Freight belt sander Chicago Electric Brand. It comes with a cloth bag to catch dust. First day, the zipper to open up the bag failed. Stitched in a new zipper... Still has a problem, you can see the cloud of fine dust when you turn it on, not cool for the lungs. So I needed to figure a way to attach a shop vac hose...VOILA! this thing! Fits small sized vacuum hoses from little shop vacs, and regular home type vacuum cleaners like Electrolux, Hoover, Rainbow, Kirby or other el-cheapo ones.You need an adapter to go from small hose to large standard shop vac hose such as the Home Depot Ridgid 6.0hp full size. This kit is an example of an adapter showing the size.https://www.homedepot.com/p/RIDGID-Hose-Diameter-Adapter-Kit-for-Wet-Dry-Vacs-3-Piece-VT1755/202077239
Vortex 30p PLA
Printed with Cura 4.1 With experimental option to make overhangs printable selected. Making a few of the resulting flat overhangs at an angle would have been difficult in tinkercad. This just cleans up a couple spots in the inside where it's not critical.
Nothing needed other than a little cleanup. This fits a little snug. If too tight (Can't guarantee tolerances on the belt sander.) Increase the scale factor a percent or two. If you don't want to waste a lot of filament to test first, print with 1 wall and 0% infill for a quick test fit. You could use 100% infill for the final print . 40% seems ok though. This part could be made with any other filament. Nylon might be the most durable. Even a stiff but flexible filament might be good too.
