I created a parametric design of a sliding puzzle and combined it with a stl generated by HueForge.

The design was printed on a Ender 3 Pro, with the following settings:

• up to 7mm with 0.2 mm layer height
• from 7mm with 0.08 mm layer height
• you can print the puzzle with a color of your desire
• color change to black after 7mm(or after layer 35)
• color change to red after 7.40 mm(or after layer 40)
• color change to grey/silver after 7.72 mm(or after layer 44)
• color change to blue after 8.20 mm(or after layer 50)
• color change to white after 9.32 mm(or after layer 64)
