Lack 1.75 mm filament bushing

Bushing and nut to pass filament through an IKEA "Lack" table. The threaded end of the bush has an M10 male thread, matching the nut.

At both ends are M6 female threads for mounting 4mm M6 pneumatic connectors (like these ).
The width of the nut and the bush is 17mm.

I use the socket for the connection between Drybox and Prusa i3 MK3. It is a preparation for the multi material upgrade, which provides corresponding bowden cables.
