Waveshare ESP32-P4-ETH version 3D printed case

[zangaby]

Hello,

Is there by any chance a 3D model for a case that would fit the Waveshare ESP32-P4-ETH board + the C790 CSI module (and ideally also an OLED screen) ?

Thanks !

I’ve already started working on the enclosure, but unfortunately, I haven’t had much time to continue with it. If anyone has the time and would like to make their own version, that would be great. Otherwise, I’ll try to find some time over the next couple of weeks and make a 3D-printable version myself.

Unfortunately my CAD skills are rather limited, but I would be happy to print and test fit the parts if that's something that might help.

Found a contractor. Case outsourced. 😂

I've made a small case for the nano. Still needs some tweaks.

Dude, looks perfect
I have designed too, but yours looks much smoother. Can we have link to download .stl?

[DaveDavenport]

I'll try to upload the design this evening. Its an openscad design.

The nano pcb fits fine, but to insert it you need to bend the case a little bit for the connectors to pop into the holes.

The pcbs are screwed down with m2 screws.

I've added the text in orcaslicer, using the gohufont unil1

If it helps anyone I've created this case for the ETH model. The P4 board was tricky to secure so be careful when removing so you don't damage it.

[DaveDavenport]

available time to work on it 😄

Ah yes I sympathise as this is a bit of a busman's holiday as well for me and kids blah blah so feel you.

[dexif]

Of course. I couldn't see a way to contact you direct but I was thinking of making an all in one pcb and wondered if you wanted any input to it?

I have just made a Hardware category for exactly this kind of thing, so a board deserves its own thread there rather than living under a case:

https://github.com/orgs/espkvm/discussions/categories/hardware

On the board itself, I should be straight with you: I am not the person to make hardware. I am a software guy :)

So you can build whatever makes sense to you ;) , and I will help from the firmware side. A board is a settings overlay here rather than code, so adding a target and publishing images for it is cheap.

I only have an idea of ​​what the final box should look like, so I still want to create cases for the boards I already have. I'll try to find time and do it next week.

Sorry didn't intend to hijack the thread. If anyone prints the case any feedback would be great. It's a snap fit case so no fixing hardware needed. I didn't put the screen in yet as I haven't connected one but if anyone needs it I can look into it. I have also received the p4-nano board this week so can look at making a similar style case if there is demand.

[dexif]

Everything's fine. This is a normal situation in a developing community. It's probably my fault for not creating the necessary categories.

Getting back to the case, I wanted to print it over the weekend, but I wanted to make a place for the OLED screen in the lid. Somewhere behind the 790 module in the corner ;)

User Fabrion365 on makerworld kindly agreed to adapt his esp32-p4-eth case for the ESPKVM project. kvm-case-for-esp32-p4-eth-and-c790. I think it turned out very well.
