This is a remix of the osVAC adapter F32-M32 slip ring and osVAC adapter base by steffen_dd. The hose connection of the first adapter was removed and an internal thread was attached instead. Together the components make a wall bushing.

I use this wall bushing to guide the suction hose on the CNC module of the snapmaker 2 A350 through the housing. This makes it possible to suction at the CNC router when the housing is closed and to discharge this to the outside.

On the snapmaker I use this suction https://www.thingiverse.com/thing:4731446. For the suction I have converted an osVAC adapter https://www.thingiverse.com/thing:4790731.
