This is a compact, minimalist wallet you can make yourself. We used a custom gradient in Chroma to create this effect.
1) Slice the STL in the slicer program of choice. This G-code file does not have to be loaded in Chroma, and goes to your printer.
2) Create a custom MSF file. Use the generated .gcode file to determine the print length and minimum layer height. The custom MSF file will be loaded into Palette+.
