Support Structure for Electronics

I saw some support structures to attach the electronics (raspberry pi 3, RAMPS, mosfet) on one side of 2020, but to be honest didn't like them... so I decided to do one from scratch. Instead of super mini M2 bolts used in the designs found around I decided to use my custom push and lock stuff. To attach it to your 2020 or 3030 just need a M5 and t-slot.

Please be kind, this is my FIRST project, I mean, just took the thinkercad tutorial and this is my first project EVER!
