An assimilated Borg version of the Retrocube Case for the Raspberry Pi 4 originally by Uncle_Gru., thingiverse:4059929. With also special thanks to dmaccallum Borg Cube shell thingiverse:1608509. The original case has also been adapted to allow for slightly more room to house a Raspberry Pi 4 board when being inserted into the case. There is also a larger opening slot at the front of the case for easy access to the microSD card. The overall look has been assimilated from the original Retrocube Case including some intentional Borg pipework on top of the fan assembly. The size of this case is approx 100mm H, W, D).

Assembly: If you want to recreate the green interior Borg lights some ultra bright green LED's will suffice along with some female to female jumper wires so no soldering is required. The LED's can be fixed in place at either side of the interior using some sticky tape. These LED's have a forward voltage range of 3.3-3.8v which means you don't need to add a resistor and you can easily attach them directly to the 3.3v pin outs on the Raspberry Pi GPIO - [do not attach to 5V or any other GPIO pin!]

This version comes with a 50mm fan hole and you can buy a 5v 50mm fan to fit inside it and fixed using M4 screws or using some hot glue. I purchased a fan from ThePiHut.com. The fan can be connected to the 5v output pin of the GPIO. The fan and cover are mounted with M4 screws. The Raspberry itself is fixed by M2.5 screws. It is advisable to use real metal screws - not printed PLA ones as these could snap whilst trying to insert or remove them.
