BIQU H2 Ender 3

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4899387.

Every single mount for the stock Ender 3 carriage has the holes misaligned. I cleaned up this design and made the mounting holes line up properly. I also modded the mount a bit so I could mount a 40mm cooling fan on the heatsink using a single screw in the bottom corner. Print at 0.2 and 100% infill.
