2025-06-24 UPDATE: Top lid should hold in place by itself now. I haven't printed updated version, but everything should be fine.
Printed with PETG
0.16 layers
2 walls
20%infill
Print with front face on the bed without supports.
Buck converter just slides in to the case very neatly. Came out better than expected.
Case was made to be hidden inside the printer. So ease of use and good airflow was in mind when making it.
