ShopVac to tool port adapter

NOTE: I'm moving all my designs to PrusaPrinters.org, this design is available and updated at https://www.prusaprinters.org/prints/96458-shopvac-to-tool-port-adapter

This is a simple, but strong shop vac to tool port adapter. Currently the following sizes are available:

60mm x 45mm
60mm x 37mm

If anyone needs a different size adapter, just give me the dimensions and I'll add it.
