Measures 10cm x 13cm x 4cm with a 5" touch display Printed with "premium" PLA on a 5 year old Wanhao i3. Nothing special. Parts used: * RPi3b+ * [5" DSI Capacitive Touch Display (800x480)](https://thepihut.com/products/5-dsi-capacitive-touch-display-for-raspberry-pi-800x480) * Heldertech RetroPSU (bought used, very hard to get a hold of) * [LP675776 battery](https://www.amazon.de/-/en/Battery-Li-Polymer-Rechargeable-Connector-Certified/dp/B09DPR4V6L/ref=sr_1_2?crid=10ZMSCTSXJRZ6&keywords=lp675776&qid=1661417343&sprefix=lp675776%2Caps%2C58&sr=8-2) * [Rii Joy-It keyboard](https://www.amazon.de/-/en/TASTAMINI01-Wireless-Keyboard-Windows%C2%AE-Integrated/dp/B07MVLTY3J) * Single DIP switch for on/off * 2 single usb ports * 10 tiny screws easily salvageable from other electronics I removed the double-stacked USB ports as well as the ethernet port on the rpi to decrease it in height. Soldered on two single usb ports instead. The receiver for the keyboard is wired up using the unused usb pins on the inside. The battery lasts a few hours depending on use, but can be charged with any USB-C powerbank. Ports: HDMI, minijack, 2x USB 2.0, USB-C charging New addition: A removable cover in the bottom of the case to allow full GPIO access. I know the bottom is not the most practical location, but it takes up the least space and it works. The keyboard comes with toggleable illuminated keys, so that's a feature too. Note: The keyboard used is of poor quality and the keys will often detect multiple presses per press. Luckily this can be entirely fixed via software using this handy tool: https://github.com/finkrer/KeyboardChatteringFix-Linux
