I got this Seeed Studio XIAO ESP32S3 for my Prusa XL, but it runs far too hot to use inside the enclosure. On the other hand, it should work great stuck to the front of my SL1S now that the firmware finally supports PrusaConnect.
Print with 0.2mm layers and whatever infill you want (even 0% is probably fine).
Due to its tendency to overheat, I wanted a minimal case with lots of ventilation and room for an external heatsink (up to 15mm wide). This is a simple friction fit that is mostly held on by the USB connection itself. It can be a bit fiddly to get the camera fitted into its slot but everything should push together with very little effort.
You can find instructions for flashing the proper firmware on the Prusa-Firmware-ESP32-Cam github page.
The main design for this include a large “tape pad” that I needed to stick it to the enclosure on the SL1S. It's an 0.7mm offset to compensate for the VHB tape that I used. If you have thinner tape, this can be configured using the parametric CAD (see below).
I've also provided a “plain” version of this case for those who would want to use it for other purposes. However, I highly recommend you check out the CAD source link below and either design directly in Onshape, or export something better suited for remixing than an STL.
As with most of the things I design, you can find the parametric CAD source here at Onshape.
