Englmaxi-style ZMK dongle case with SSD1306 & Xiao BLE (no soldering required)

Wanted to add a SSD1306 to my ZMK dongle, most existing models are for n!n clones but I wanted to use a Xiao BLE board on this one.

Englmaxi's repo has a basic shape, but doesn't have enough room for dupont wires, no easy access to Xiao's built-in reset button, and the case isn't really secured, so these are what I tackle this time.
