Geologist or Rock Hound Gift, I Collect Rocks

Both .stl and .3mf are attached. I printed mine using Polymaker PETG on an OPXL 5H using .4 nozzles,  and .25 layer height. In addition I expanded the first layer to .25 to help with adhesion for small details. See the attached screenshot for setting up multicolor printing. Basically, objects with an ‘M’ prefix are mountains, with a ‘P’ prefix are the plate/background/inside letters and the text is itemized by text row number and appended with the letter. If you use filament with higher transmission levels then you can hang it in a window.
