I followed https://www.youtube.com/watch?v=0Sla-vIsvh4 to add a colored inlay to the case:
- Arrange both models in your slicer so that the inlay fills the void in the top (if you center both models, it should be a 23.7mm offset to get them perfectly aligned)
- Slice and print just the inlay. You might want to tweak your slicer settings to print a little slower for better build plate adhesion
- Once the first print is done, quickly start heating your build plate again to maintain adhesion
- Slice and print the top in the correct position with zhop set to at least 0.3 mm (assuming your initial layer height is 0.2 mm). That'll push the print head up to 0.5 mm, which should just clear the inlay which is 0.4 mm.
The author remixed this model.
