Adafruit Feather case for a FeatherWing stack
An enclosure built around the Adafruit Feather form factor: 50.8 x 22.8 mm boards with 2.5 mm mounting holes on a 45.72 x 17.78 mm pattern. The base carries four M2.5 standoffs 3 mm tall, a USB-C or micro USB opening on the short end and a slot for the JST battery lead, while the walls rise 24 mm to clear a Feather plus one stacked FeatherWing on headers. The lid has a 24 x 14 mm window for an OLED FeatherWing and a slot for a whip antenna on RFM or LoRa variants. Walls are 1.8 mm and everything prints flat without supports.
Because stack height depends on which Wings you use, a downloaded case is usually too short or too tall. In SpeakCAD you describe the boards, preview the case free in the browser, change the height or move the battery slot in the chat, and download the STL when the assembly fits.
