So I found the nice scaleable mini-nuke by Exustio, and went to edit it for my own personal remix(es). I noticed that the original (itself a remix) was hollow, so I decided to repair it and make it solid (better for further remixing and such).
This model is scaled to be 200 mm tall.
Fixes I implemented:
Reduced in Meshmixer to pare down the file size
Solidified using Tinkercad and then exported again (you don't want to know)
Run through Netfabb Online to smooth out some small errors and artifacts from the original file (which also significantly reduced file size)
Checked in PrusaSlicer and Tinkercad for visually notable issues (none found)
