The “Stubby”, the shortest connector for @PeterH CAMLOCK System i could make. You could probably cut it a few mm shorter by removing the flange at the top if you want.
Made to fit the dust port of a Makita DRT50Z trim router. Should fit both the regular attachment and the plunge-base.
Fits well without glue or tape, just press it onto the dust port.
The author remixed this model.
Made the adapter slightly larger to fit the dust port of my Makita router and cut it shorter, I call it the “Stubby”.
