Thingiverse user patkan made these colorful Pi boxes from the laser files for the Adafruit Pi Box enclosure for Raspberry Pi® Computers.
Adafruit Pi Box – Enclosure for Raspberry Pi. Keep your Raspberry Pi® computer safe and sound in this lovely clear acrylic enclosure. We designed this case to be beautiful, easy to assemble and perfect for any use (but especially for those who want to tinker!)
The case comes as 6 pieces that snap together, made of crystal-clear acrylic. This ingenious design has no screws or standoffs and there are cute little feet cut into the sides so that it stands up above your desk. There are engraved labels on all the connector slots. You can use all of the connectors on the edges of the Pi: HDMI, Audio, Video, SD slot, micro USB power, Ethernet and the two USB ports. We also added a slot so that you can connect a 26-pin IDC cable to the GPIO breakout pins on the Pi and pass it though the case. For more advanced hacking, the enclosure is designed so that you can remove the top piece and plug any sort of cables you wish into the breakouts in the middle. The case is airy enough that no additional vents or cooling is required – we tested the enclosed Pi over a 24 hour period at full load with no significant increase in temperature.
The Raspberry Pi® is a single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of stimulating the teaching of basic computer science in schools. The design is based on a Broadcom BCM2835 system on a chip (SoC), which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 256 megabytes of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage. The Foundation plans to support Fedora Linux as the initial system software package/distribution, with support for Debian and Arch Linux as well – Wikipedia.
