Added pictures using a metallic color changing PLA I had laying around with Bambu Labs black PLA-CF for the web. PLA-CF works really well for long bridge features!
First attempt at creating a ‘suspended’ model. Skull and frame were printed in Ziro Gradient PLA: Season-Winter. String grid in Sunlu Clear PLA (my favorite clear PLA). This profile is optimized to reduce color transitions between the grid and the rest of the parts so doesn't take forever to print. The grid layers, the frame, and the skull are exposed separately in the object list though so you can play with colors as you like.
Enjoy!
