Update 2024-08-12

Added EVA34M1 compatibility (https://jon-harper.github.io/E34M1/)
To increase stability, the motor mount (motor-mount-eva3vm1.stl) now has an additional leg that mounts to the top module of the EVA34M1 https://jon-harper.github.io/E34M1/modules/top/

Make sure the top module has the heat insert in this hole. Unfortunately, the heat insert comes in from the bottom.
I've used a 18mm M3 fastener for this.
