Every build starts somewhere. This one started with a display: a 1.28" round GC9A01 TFT, chosen because a humidor controller should read like a gauge — glance at it across the room, know your humidity.

Problem: nobody makes a mount for this module. So the enclosure came first. I modeled a lid with a circular cutout and a snap-fit bezel to capture the display, then ran test print after test print until the module seated flush without pressure on the glass.

These photos are day one of the project (mid-July): the bare display module, the first printed lid with the display cutout, and the bezel fit checks. Next up: wiring the ESP32.
