This is a basic case for the AVR Dragon with mounted ZIF-Socket. The AVR Dragon is delivered without a case so I designed one myself. The AVR Dragon is a microcontroller programming device from ATMEL. (i.e. Arduino uses these microcontrollers) For details of this device see here: http://www.atmel.com/tools/avrdragon.aspx So why is this case special? The attached photos show the parts of the case with my AVR Dragon and the different mounting possibilities of the 'wing'. Thank you for visiting! Chris I printed the case without support, with 20% infill and 1mm walls on my Ultimaker.
