osVAC Base Adapter Step-file

I liked the idea of having a base Adapter to build my own Adapters. I used the base Adapter from @steffen_dd but the included fusion 360 file seems to just have an stl Version inside. (https://www.thingiverse.com/thing:4671596) so i recreated the base adapter with help of an schematic of the osVAC project.
