Odroid C2 Case (120mm fan cooling)
Description
Based on the original .step file that hardkernel provides (the original didn't fit together properly when printed). I modified the original design to have more cooling holes on the top and side to accommodate the active cooling, and to piece together more snugly. Top bolt the air duct to the top, and the fan to the air duct, I used meccano bolts, which I have plenty lying around. The hole sizes for the fan and air duct are 4mm in diameter. The hole sizes for the base screws are 2.5mm, Recommended screw size for the base are 2mm diameter, 5mm in length (max), and max 5mm diameter head size. Wood screws for the base are preferred, but I didn't have any so I used some screws from an old laptop which worked fine. All hole sizes can be changed if you want to, I've uploaded the .step file for easy modification. All objects can be printed fine with 0.2mm layer height. I was able to print the air duct without any support material. I used 2 perimeter shells, printing from the "inside-out". There was a little bit of warping on the outside corners towards the top, but it's good enough. Some rubber feet should be used to reduce vibration sounds and lift up the odroid to utilize the bottom air vents. Also it's easy if you wish to run the cooling fan via USB, although it will most likely run at 5V instead of 12V. There are plenty of tutorials on youtube about converting a 3 or 4 pin molex fan to USB. Doge donations: D5cqNG1nHCRWeyFHv5LaJNrMP54MVyM2Az Much appreciated!
