So this is for a specific situation. My board died and I replaced it with a Ramps 1.4. It's a lot taller and my Mini could no longer sit flat, so eschewing the base plate I made this to slide on the inside of the front and back steal plates and sit there. If you're in a situation for that, this might be for you!
UPDATE: V2 of the legs are here! Added a small lip to "help" with them sliding off once on, not sure if it truly will work yet.
Also increased the height by 1cm. For better clearance for the RAMPS board.
Lastly, decreased the space in the clip itself so it's a little tighter.
Anyway, simple addition if needed. And easy to modify, made in fusion 360. If you find the hook too loose, keep in mind that your material may contract over time, that said, lining the inside of the feet with a piece of painters tape will stiffen it up.
You can print this on it's side with no supports for the lip overhang.
