Remixed the original model in Fusion 360 so it could be repaired and remeshed as a single head.
Created the .3MF with a hollow rod to unify the internals into a single body, but still look like 2 on the outside. This makes the body extremely rigid and durable, esp in this orientation.
This can be printed hollow with only infill at the top. Lightning is the current fun sparse infill.
Print times are much better on larger nozzles:
0.4mm ~36hrs
0.6mm ~20hrs
0.8mm ~12hrs
The author remixed this model.
