Bench Grinder vacuum cleaner dust attachment duct

thingiverse

I designed this to grind and sharpen carbide tools with a cup CBN wheel because carbide dust is a health hazard. Upright vacuum cleaner hose attachment to my 8" Variable speed bench grinder. This model has several vent slots at the bottom of the wheel covers. My grinder is sold under many many brand names around the world with slight differences so I included STL files with no holes so perhaps you can scale and drill them to fit your variation. This mounts by slight flexing around (over) the existing bolts which hold the wheel guards together. I used a step drill to finish the hole diameter. Print with a flame proof filament and use a flame proof vacuum cleaner with nothing vacuumed up that is flammable. Sparks are hot and stuff can catch on fire if things go wrong. Print these with a wide brim. Flip on to the flats which make all the surfaces 45 degrees or more vertical so no supports are needed. Push the tubes together and the layer lines will secure the assembly. Designed in Fusion 360. Printed on a CR10S pro with a custom direct drive mod. Have fun -Peter
