Monoprice Select Mini Z stabilizer and 3rd bearing bed mount

Where to begin, I named this my Colossal Mini V2. I used this mount in conjunction to support the extended bed which also turned into my dual z motor concept V2 mini. I expanded the bed to 300 x 300mm, added a third rod to support the bed and mounted the bearing cup (not my design) on top of the support. Take a look at the pictures, it explains it better.

Infill is up to you.
