In this project we're building a portable Raspberry Pi using the model A+, PiTFT 3.5” display, Powerboost 500C and a 2500mAh lithium polymer battery.

We designed this very simple case in CAD - It's a two part enclosure that's fasten together with screws. All the components are panel mounted and fit nicely in a small little enclosure.

This is a great starting point to build on top of, because you can modify the parts to fit your project and reuse any components - It's a very modular design and it's open source so you can make it yours.

Hi, printed this model and need exact dimensions of the opening screen opening and positioning. I have printed with is and fits. You screen perfect but need the dimensions so I can adjust my screen to match my design. I'll look forward to your reply.

Really wishing for a Pi 3 version... :)

nice ! but a Pi Zero version where awesome :D

Wish they Would update the File's for the PI2 and now the PI3 or sale the case atleast

I made one but it does not fit correctly... I printed with a CreatorPro 3D printer. I'm using a Raspberry Pi A+ and the TFT 3.5" Touch Screen for models A+ and B+, What I did wrong?


The circuit diagram and how everything is wire in the video do no match. For example, the jumper wire connections are in different places. There is also an extra third red wire connected to the board in the video that is not shown circuit diagram. Can you tell me which instruction sI should follow - the video or the diagram? I formatted my 64gb SD card as FAT with PiA, but all I get is a white screen and it never boots. Any ideas? I used the Jessie boot version. Thanks

Hi there, we recommend following the diagram in the written tutorial. We suggest using the 3.5" PiTFT ready-to-go image available here: https://learn.adafruit.com/adafruit-pitft-3-dot-5-touch-screen-for-raspberry-pi/easy-install


Could you please post the stl file for the PI B 2 version as I can't read 123dx files.


printed this in a few colours. all came out great. Black showed alot of the flaws (things like curves etc) but may just be my slicr settings. ended up going with fluro green which looks great.
My printer makes little knubs where the standoffs are, does it all teh time when making small circles, just some resiude from teh pla left over. so i had to sand down the knubs to get the screen to fit, wasnt too bad.
Power switch socket needed sanding too to get it in but it was ok.
The thing is awesome, but i have no practical use for it what so ever. was great to build though.

It is possible to have thing files for your 2,8" PiTFT ?


Yeah. the files used to be there from what I belive, but they were removed. Not sure if they fit properly but adafruit must have removed it but not updated the desc.
fits the pi A perfect..lol

I printed this last night - Sept. 8. It doesn't come close to fitting the Pi 2. The raised flanges in the interior prevent the Pi from sitting level in the bottom. The power, HDMI, and audio outputs don't fit into the holes because the interior vertical flange. Also, does anyone know if the script has been updated for the #2441 touch LCD? Lots of comments that it was broken and kills the kernel.

i would like to make this with the raspberry pi 2 will the stl files work with that as is or do i need to mod the case to fit

So I paid through the nose to get this printed and started screwing in everything and the standoffs broke. I didn't exert any force or anything and they just broke off. Now I come back to see the comments that they couldn't get all the components to fit properly, wish I had gotten that far. Has anyone improved this design or possibly know of an off the shelf case that will work?

Hi, the Pi 2 versions don't seem to fit the battery. The jumper wire connections to the tft stick out into the battery and the pi 2's usb drives take up the rest of the battery space. Any ideas?

Clip the PiTFT breakout pins off on the screen and solder directly to #2 and #6. Worked for me. Im using the B+. Battery fits between the screen and the Pi, just over the clipped off breakout pins behind the powerswitch.

Same here... Even if you can somehow squeeze the battery on top of the pi 2 or B+ the pins from the PiTFT won't let me close it. Any solutions so far? Regards!

This printable case may fit the Pi 2, but it doesn't change the fact that pitftupdater.sh script on github hasn't been updated since Dec 19, 2014 and doesn't work with the Pi 2. BTW your PiTFT35R_raspbian custom image doesn't work either. When will adafruit be updating the script/image for the PiTFT that works with the Pi 2?

Hi, Can you share you print settings? material type/temp, infill %, infill type (concentric, rectangle etc), # perimeter walls, etc. Thanks!!! I'm still new to 3d printing...

After having my local makerspace print this enclosure for me, I definitely see room for improvement and to make it smaller. I wonder why the standoffs to connect the two sides need to be separate standoffs and not integrated into the corners of the case. Also in the redesign for the Pi B+/2, the hole for the powerboost screw should be in the other half of the case as well as he forgot to merge in the interior part of the opening for the power boost. Nice idea, after the first one is built I plan to go in an clean up the design.

To use with the Raspberry Pi 2 B all you need is to download the Touchpi2 top and bottom files and print those?

What OS do they use for the final product? (The OS in the initial picture)

Not sure if it's my printer (CubePro Trio) but the mounts for the screen are off by about 2mm, which in turn means the two halves of the case don't sit flush.

How long will it run with the recommended battery?

The parts should be here on Friday, I plan to test with both the B+ and the 2 and will leave my battery times here.

Did you have to modify the screen pins to get the battery to fit with a B+ or 2?

Any chance I can get the metric measurements of the screws needed?

There on adafruits Web site

Ah yes, so they are! Thanks
