Can someone suggests what are the recommended infill and layer height to a 3d-noob ? thank you in advance

This model is not fully compatible with Pi 3+. There are PoE pins which prevents the lid to close. 5mm drill comes to help. As expected, support columns are pretty britle, so even with tender inserting of Pi I've lost two. I'll probably replace it with magnets.

EDIT: anyway, it is great case, thank you

tested it with prusa i3 and PLA today
bottom part "CaseBottom-_With_Vents" came out with 2.2mm poles, which fits nice into 2.75mm raspi mount-holes
holes in the top part "Case_Top-Heatsink_Camera__Display_Connector_Cutouts" came out as 2.9mm and are too loose to hold the 2.2mm poles
otherwise a really nice case

Works great! Many thanks.

Excellent design, printed mine straight from your files on a prusa, snapped it together and was off to the races, not sure why folks are having issues with it, i posted pics and my build settings.

If you drop this in Tinkercad, and make the bottom piece 17.5mm tall, it will match up perfectly to the tops of the USB ports and Ethernet jack. I also made the hole for the Heatsink just larger than the outside dimensions of a 50mm Sideblower fan output, and superglued the fan to the case. My Pi3 is running very cool. And with a Pi3, you can run the TWO LEAD (Only) fan wires to the 5v and ground pins on the Pi, and run it 100% of the time with zero noise... I mean it's completely silent, and I had to touch the fan to make sure it was spinning... You don't have control over fan speed, but the Pi3 definitely has the power to spin the fan at a decent speed, and keep itself cool all the time.

Could you please provide the source files? I nearly destroyed my Raspberry Pi 3 while trying to fit the lid on the case. I printed it on a Ultimaker 2 which is very precise but the snap-fit posts are way too big to fit the lid.


Take a round needle file to the mounting holes on the Pi and it will slide right on as printed...

I had the same issue using "CaseBottom-_With_Vents" and "Case_Top-Heatsink_Camera__Display_Connector_Cutouts" on the Pi 3. My posts came out to about 2.75mm, which is the size of the pi mounting holes, but I needed a bit more clearance for them to fit in the pi and the top part of the case where the holes were even smaller. I would move the vent on the bottom piece under the chip on the board and the GPIO cutout is too small if you were to attach a 40 pin header. Otherwise everything fits pretty well, and I really like the slim design and easy access to the SD card.

Awesome design. Thank you. Works great.

The BEST case for the raspberry pi 3. Best airflow over heatsinks while also being nice and slim. Thanks!
