The display stand is meant to print with a 3 filament color swaps.
0mm - first color (black)
16mm - second color (brown dirt, tan sand, or glow in dark ooze)
22mm - 3rd color (silver, gray, gold, bronze metal)
The coin is meant to print with one filament swap.
3mm - swap
(I included the stand with and without helper tabs - the tabs helps keep the print from lifting.)
