I wanted jetpacks for minifigures, and then came up with a way to make it even more awesome. The big figure is the same model scaled up to 19 mm for the neck hole, or whatever yours might be.
Prints great with not many extra settings and works well when printing more than one at a time to let it cool, although that might not be a problem if you have a layer fan.

some have suggested a smaller layer height looks good, this one was printed a while ago on my less-dialed-in printer so I don't have pics.

if anyone does this in resin I would like to see it but no pressure :)

have fun and happy printing!
