thingiverse

This is a case designed for using an Ikea Koppla USB charger (design for the EU plug version, three USB ports) for power supply of electronics projects such as small sized Arduinos or ESP8266. The USB cable is covered inside the case that is press mounted on the USB charger. There's a removable lid on the side. There are different sizes available, sized according to the electronics case part (40mm version in the images). It's recommended to cut an USB cable and solder 5V to the electronics board (if suitable) to reduce the required size. There's a 4mm wide opening in the back for cables and openings on top and bottom for ventilation. Fusion 360 file available at https://a360.co/2HRkkTd
