Hello, these pics are a few years old but they show the Tank Mark V in 1/72 that I made by remixing somebody else's model.
I don't have my own 3D printer so I used the one at my local public library. It's not a very good printer; it is the FDM type (filament) so it doesn't do a good job with small details and it leaves layer lines, but it did prove that this model works, and I am reasonably pleased with the result. I printed the sides twice; once flat to the screen and once at an angle. The flat print messed up the details a lot, but the angled-print looks good.
Total cost was either $2 or $3 because the library charges $1 per hour of printing.
The model is on Thingiverse, and could be on Landships as well if anybody thinks it's worthy enough! I would love somebody with more talent to take it and remix it to improve it.
