TPU/PLA Hybrid Box - Heart Version

This is a single print hinged box that is printed with TPU for the first three layers and PLA for the remaining layers. It works well as a case for wired earbuds or other small items. They fit pretty well in the pockets of my jeans.

Temperatures: ~210C nozzle temp for both filaments, 50C bed temp

Infill: 100% (don't worry, this print is almost all perimeters)

Layer height: 0.2mm

Print speed: I use ~30mm/s for all the TPU layers.

Flow rate: I increase the flow rate from the default 95% up to 105% for the three TPU layers and the first PLA layer

Supports: No

Printing surface: Prusa textured steel sheet

Filaments: PRILINE for the TPU, various brands for the PLA
