This is a case for the Raspberry Pi 3 B.

This came as a challenge from a friend of mine who wanted a secure case, but did not want the bulge of external screw, like on my previous case series: Safe and Secure Case which can be found here: http://www.thingiverse.com/thing:423216

In this iteration, I decided to use M2.5 socket head screw, so this meant I could use the holes in the motherboard to secure the case in place. Hence, this is the result. The case is 20 mm high and about 2-3 mm thick. This make for a very compact case.

I'll add more top and bottom design upon request.


Edit 1: Added honeycomb top upon request.
Edit 2: Added 40mm Fan top upon request.

Print Settings










This case is designed to be printed at 0.25 mm for layer height.

It uses 4 x M2.5 20mm socket head screws to secure the case.

I printed mine at 80% infill.

I only print in PLA, and this case has 0.2 mm 0.25 mm in tolerance, which means, if you ooze too much or are using ABS, think about enlarging the print by 1%.

Also, any brim used, or first layer being squashed a lot, be prepared to use an X-Acto to remove the extra plastic for the screw head and nut traps.

There is a 0.25 mm layer of plastic that makes the transition between the 8 holes and their respective shafts. It has to be removed as well.

How I Designed This

This is designed with Fusion 360.

The Fusion 360 source file is included, but remember, Fusion 360 cannot open a local file, you must first upload it to your cloud in order to see/edit it.

Great case! Exactly what I didn't want to have to do myself.

Hi Jayftee,
I printed one for my new Pi3 B+ and it doesn't fit 100%.
Had to sand away a part of the smaller strut (between NW+USB) because of an especially bulky smd-cap.
Still looking for the other place that gets in the way, but suspect the other strut.
Nonetheless, thanks for the great slim design.

I had the same issue, but a little clipping and sanding did the trick. It is definitely a tight fit - but that makes for a nice small footprint also! Check your posts/screw posts, I had to take a little off the posts to get the fit I wanted and I also found that the "walls" (at the ending points) had a couple of bumps on them from my printer.

torgefaehrlich I hope this helps you a little!

Ich habe dein File etwas abgeändert für mich verwendet, vielen Dank für die Vorlage.

Hi, very nice case!
Can you create bottoms with closed sd card?

Source file is included, have a go at it :P

Does this fit with heatsinks? I'm hoping it does.

It does as long as tour heatsinks are not taller than the usb ports

any chance to get this without the audio and video ports... dont need them for my use.. just power and USB... have even been thinking about removing the network port on mine for octiprint because i only need 1 usb port

The Fusion 360 source file is included. If you cant use Fusion, feel free to modify the stl files directly.

This is going to help me a lot

I really like the minimal design and tight fit. Nice work. Thanks for including options (logo, vents) in the files!

Glad you like it.

Very nice case, could you add opening for GPIO pins and Pi Camera ribbon?

If you look closely, there is a top for that, its not pictured, but its there in the stl you can download

Ill see if Lowes has some. I also want to finish it somehow, since it looks a little grainy at .25 height.

Nice... I printed one but don't have M2.5 Screw laying around :(

If you look at my other cases, they use M3.....

That is what I had to use - local Home Depot didn't have the M2.5

Thanks so much for the top with fan option. Making it right now.

Very nice work. Could you please add a honeycomb top option like on your B+ case?

Its been uploaded, I hope you like it.

Looks great, thank you!
