Raspberry Pi Cool Case

thingiverse

I was tired of looking for 5v powersupplies with enough power for using with raspberry pi. I was also tired of using this shitty micro usb plug. So I created a new raspberry pi case with integrated cooling fan and step down converter. Now it is no problem to power the pi, a fan, some leds and all the pheripheral gadgets you want to use. I use an 12v 1.5A power supply and a lm2596 step down converter to power the pi. These step down converters are usable up to 3 Amps but then you have to use a heatsink. Or you use the XL4015 Step down converter. They can be used up to 4.5A. So it is no problem to overclock the pi. To built this case you´ll need a 3d Printer, filament, m3 x 6mm screws and m3 nuts to mount the pi and the step down converter and m3 x 16mm screws to mount the fan and the top of the case. I use in the prototype case a 40mm fan with integrated blue leds. In the second case I use a silenced 40mm fan and two pieces of led strip, glued beside the fan. Both versions look cool. the power switch can be found here: https://www.reichelt.de/Wippschalter/WIPPE-1803-6102/3/index.html?ACTION=3&LA=2&ARTICLE=154419&GROUPID=7596&artnr=WIPPE+1803.6102&trstct=pol_14 or this one: https://www.reichelt.de/Wippschalter/WIPPE-1801-6115/3/index.html?ACTION=3&LA=2&ARTICLE=108235&GROUPID=7596&artnr=WIPPE+1801.6115&trstct=pol_10 I soldered the power supply directly to the switch and the step down converter. If you want to use a DC barrel to connect the power supply to the raspberry pi, feel free to drill the hole to the right measurements carefully. Be sure to set the step down converter exactly to 5V before you power your pi !!! If not, it may cause damage to your raspberry pi. Be sure to connect both ground connections (- in and - out) of the step down converter together, to stabilize the power output. But only the grounds, not the + side !

The blue Fan can be found here: https://www.conrad.de/de/pc-gehaeuse-luefter-akasa-ak-160bl-s-blau-b-x-h-x-t-40-x-40-x-10-mm-998689.html Step down converters can be found on ebay or here: https://www.roboter-bausatz.de/search?sSearch=step+down When you want to assemble the pi and the case it is better to put the pi first with the usb ports in the holes and than press a litle bit so that the earphone jack and the hdmi port can snap in place. If there are any questions, feel free to ask. I wish you a lot of fun with this case. Best regards PB
