Not done yet, but my attempt at a design is attached. I’m trying to use an o-ring (AS568-337, 2.975ID x .210CS) instead of vacuum tape. Might work as-is, but haven’t tried printing it yet as I still need the hardware used in the DIY:

Bit of a hack, but might be useful as a starting point for someone with actual CAD/CAM skills.

P.S. Zip contains .stl, .step, .sldprt, and .dxf files exported from the Onshape file.
