Guide tube connector for M10

This is a guide tube connector setup for an M10 fitting for this amazing MMU spool holder: https://www.thingiverse.com/thing:3228827 . I had several M10 fittings laying around and wanted to use them with this spool holder design, but it didn't include an M10 version. So I took the STL and borrowed an older M10 design and merged together the STL files.
