CHIPbag is a customizeable case for Next Thing Co's C.H.I.P..

Options in Customizer, or by downloading the attached OpenSCAD file, include:

Snap case, Standard or Low-Profile design
Openings for headers
Opening for battery connector
Screw mounts added to sides
Bitbeam added to sides or back
Building bricks added to sides or back

With my printer, the board fits snugly in the case with the given dimensions, and cannot be shaken out. I haven't made prints with all of the options yet and still have some tweaking to do (particularly to the gridbeam spacing). Expect updates over the next couple of days.

Some options will require supports.

Your best options right now are the CHIPbag Snap and the CHIPbag Snap with Bitbeam, for which I've attached STL files. I'm still making lots of changes to the OpenSCAD file, so expect things to not always work correctly. There are some variables which do not yet do anything at all.

I'll be posting updates to the CHIPbag and my experiments with the CHIP at Applefritter and on the CHIP forum.

This project uses the BitBeam and Universal brick builder modules.

I damaged my CHIP trying to insert it. It was a standard print, so the ridges may have caught on to a delicate component (a small tab-looking thing with a super thin copper wire wrapped around it). I should have used a more detailed setting. Also, I couldn't get the thing inserted.
Lots to learn, I suppose.

I'm sorry to hear that. Sounds like your case is definitely too tight. It should slide in without any force.

Well, it was a quick print. Low resolution, if you will. I think that's why I couldn't get it to slide in. No where close to a smooth finish. I should have used a higher detailed print.

I originally printed these on a TinyBoy, where the cases came out with a good fit. I've tried it now on my FFCP and Makergear M2, and it's too tight on both, so I think my TinyBoy may have been a bit miscalibrated. I'll make the case width a hair wider.

I am having issues with getting the top of the T to print correctly. I am doing everywhere support with a raft. It is standing up with the cutout like a T. Any tips? I am also using cura PLA 195 deg nozzle 60 deg print bed. Is there a better slicer that is recommended for this T situation that offers a better support or do I need to flip it another direction? Also Thanks.

I print mine in the same orientation. I've used both Cura and Slic3r without any sort of unusual supports - a single column for each side of the T does it for me. Can you post a photo of the problem you're having?

Have you had a problem with overheating due to lack of airflow and convection abilities with the solid top?

I haven't, albeit I don't have any running 24/7.

Does it fit the latest C.H.I.P. with the repositioned JST port and plastic case?

It's been updated for the current CHIP.

My December board still hasn't arrived. If you could sent measurements, I could adapt it for the new case.
