osVAC Female-Female connector

When I found quite a few “conflicting” osVAC add-ons I decided not to try and fix it but just create a 3D model for it :-)
It connects two male osVAC ‘things’.

• PLA 0.20mm
• No supports
• 15% infill (not a lot but so far it works fine)

Note that officially (see this video) it should be like this: 
- MALE adapter on machines: the “to be suc.. vacuumed” device
- FEMALE adapter on your hose: the “vacuuming” device
