My electric handplane makes a mess when in use and the port is a very funky shape, so I put my CAD to the test and came up with this beauty!
The planer is a Black & Decker 7696 3 ½ inch planer and the vacuum is Rigid with the 1 7/8" hose… ecosystem? However this adapter is designed for the female end of the hose, the end which normally would plug into the vacuum itself.
