Mini '2-piece' unified Mjölnir

Remixed the remix for smaller printers.

File is a .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 ~17hrs

0.6mm ~12hrs

0.8mm ~8hrs

EDIT: Updated with 3 sizes:

180mm for mini printers

210mm for non-prusa

250mm for mk2/3/4 size beds 
 

Smaller for smaller printers.
