This STL file contains 10 25mm wargame bases with a scenic natural pattern. The bottom of each base prints with a pocket for a magnet so your magnets never come off. I recommend 10mm x 2mm magnets for these slots.
With the Mars pattern, you'll need to use an SLA printer or something similar to get the smooth look of the renders, but I think they still look good with FDM layers. I will post some prints soon from both FDM and SLA printers to give a sense of what you can achieve.
