This is a quick mount i printed for my 5HP rigid vac. Helps with dust, doesn't require a skirt and keeps dust down! Pretty simple. Still working on it, getting better angles and closer, might add a clip-on shield around it....Printed in ABS, printed on it's side with support. The version 4 doesn't require any cutting of the stock vacuum end. The version 5 is closer to the bit and requires a small semi-circle cut. Also use a couple M3 screws to secure the vacuum.
