Two different options for 8020 mount for Witmotion WT901C . This was designed mainly to mount this to a simracing rig to keep the unit solidly attached with no shake.

Basic version should do the job. It prints much faster. No supports needed for the basic one.

I made the over-engineered version mainly because I'd never made anything with a thread before. But it does work and can be screwed down for extra tight fit. The cone in this STL is to force the printer head to move away to give the plastic time to cool on the threads (there's probably a better way to do this but this worked for me). For the over-engineered version. Use supports for anything touching the bed only (make sure supports aren't used for the threads)
