Super Mini Axolotl 100% is very small, so i wouldn't suggest smaller but you can go bigger. In fact if you go bigger you'll be able to incorporate more colour options that wouldn't print at 100%. The other model in the photos was printed at 200%. Where the spine, eyes and fins can all be coloured as usual as the model incorporates separate bodies. Ive made sure that the small size prints perfectly with standard settings, so 0.4 nozzle and 0.2 layer height. 10-15% infill. You can fit a large number per build plate. around 35ish. I have also included a keychain version.
