I made this box to hold my three Raspberry PIs since i was running out of space. It has a 5 amp 5V power supply with one or two fans. The air flow is channeled along the pis and through the power supply for optimal cooling. There is also a voltmeter and ammeter to monitor your consumption. This is still in trial and error phase so print with care.

05/21/18 - Warning, it turns out that one of the cooling channels interferes with the power display, I will be fixing this and uploading the new file... If you have already printed it, you will need to trim the cooling channel.

05/22/18 - Fixed placement of the display and made numbers thicker and deeper.
