This is a osVAC M32 adaptor for Makita SP6000 track saw vacuum cleaner outlet. The adaptor has a cone shape (starting at 35.4mm and ending with 35.6mm) so that is sits tight in the original adaptor. It can be use on other tools too as long the insert diameter is around 35.5mm. The adaptor may kept inserted while the saw is stored in the macpac box.
The author remixed this model.
Used the generic M32 coupling and added a cone 35.5mm insert. Removed text as I find it ugly when printed.
