Prusa Mini+ Faceplate with boat on a filament sea

Ok, so I'm very new to modeling in general, but specifically to remixing. 

If you try to slice this at 0.2, the original design will show through.

I printed mine in PETG, but only because I wanted it to match the rest of my printer. PLA would probably be better, or you just have to be a better maker than I am, and have your PETG settings dialed in better.

I'll include my gcode FWIW
