Hemera Mount for Ender3 Pro (optional: with BLTouch)

Parts to mount the Hemera on the Ender3 Pro! More compact than the stock design while remaining sturdy. This is a remix of https://www.thingiverse.com/thing:4061250 that do 2 things:
- Make the holes on the Hemera Mount for the BLTouch hex nuts bigger so you can actually fit M3 nuts
- Rework the BLTouch mount so it doesn't touch the stepper motor before the mount touches the Y end stop

I also did write up of tips at https://github.com/Viq111/HemeraEnder3 that I highly recommend reading before diving in.

Printing:
- `HemeraMount.stl` + `PartFanArm.stl` needs to be pretty rigid so do at least 50+% infill cubic
- `PartFan.stl` doesn't have to be strong so 10-15% infill is fine. Be sure though to print with a material resistant to heat (PETG for example, no PLA!) since it will be close to the nozzle
- `BLTouchMount.stl`: 50+% infill cubic but also you'll need a support part enforcer (see image) to make it easier to print
