OnePlus 3/3T case with maze pattern

thingiverse

This is a recreation of lynx7878's incredible design. The phone case can be printed with one nozzle by printing the maze pattern (green) first and then printing the surrounding area and case (black). These different colors should be exported as separate G-codes. Always use the "Z-hop when retracting" setting in your slicer when you print the second G-code to ensure a smooth finish.
