This is a remix of https://www.thingiverse.com/thing:2750908 originally made by parhamdb. It also uses the mounting tabs from https://www.thingiverse.com/thing:1686028 by mmoore0.
I've got a Monoprice Maker Select V2 (RAMPS) and I really liked parhamdb's original model because it offered direct chassis mounting, rear plug mount, plenty of space for wiring, and was also nice to look at. Unfortunately, my Sompom (stock) power supply died, so I replaced it with a Meanwell NES-350-12. This new PSU didn't fit in the original model since the model was designed for use with the MMSV2 stock supply.
I liked the fit of mmoore0's Meanwell Power Supply Cover, so I combined the two! With this remix of two awesome models, I have finished moving all components out of the original control box and mounted them all to the chassis of my RAMPS MMSV2 similar to how the Prusa does it.
I used slic3r PE to chop the models at specific heights, then used MeshMixer to stitch them together. I had to expand the X a bit on the base so that the Meanwell tabs would fit on top of it.
