An adapter to mount the Dust Commander Anti-Crush Valve to a 40mm plumbing T-Piece. It's a snug fit on the plumbing piece and seals the pipe nicely. Replaced a 3D printed valve that was too loose and was partially open during normal use of my dust collector.
Printed in PLA at 0.2mm layer height and 15% infill. The holes for the two securing screws break into the thin walls a little, but it doesn't affect the security of the device.
