MX Ergo 65° Stand

I found the base plate retention mechanism on the original 65° Stand to be quite hard to both print cleanly and use in practice, I found that the 40° Stand's more liberal use of magnets created a more capable retention mechanism, so I combined them, keeping all the features of the 40°, I also expanded the inserts for the magnets to all be 8mm as that's what I have most rn.
