2 versions for each AMS/MMU and Color Swap. CS are labeled as well as KC for keychain. AMS version print Face Down with .2mm layers, I also tweak the line width to .24 for the first layer and .3 for all other layers, this includes infill. 4 bottom and top layers, the 4th bottom seals in the color and fills in any gaps. Each model is separated into sections where appropriate and a backer. The color sections are .6mm thick the backer is 2mm. I have included 3mf files for both AMS and CS. Some AMS are 4 color but can be convert to 5 easily. I included some 5 color options too. These can be scaled up, I don't recommend scaling down. Be mindful of the Z when scaling up, It doesn't need to be 10mm thick, Z can stay at 2.6mm. KC - Keychain (it has a hole) CS - Color Swap (No AMS or MMU needed) Layers to swap are at 1.2. 1.6, 2.0, and 2.4 but vary depending on the design and amount of colors, check this before printing. If you use the non CS STL's do not resize any objects, it will ask you. I attach a 20mm square magnet to the back. I hope you enjoy these models. 0.2mm layer, .24 first layer width, .3 all other layers, 2 walls, 15% infill, 4 Top/Bott for AMS/MMU. CS - .3 widths is fine. You are not printing these face down. Also depends on the model some can get away with standard .4 widths.
