Prusa Enclosure Mount for ESP32 TimerCam

I needed a simple case to mount my ESP32 TimerCam to my Prusa Enclosure and leave room for the USB power cable to be connected. The result is this very compact and inexpensive WiFi print monitoring camera. Parts needed:

• M5Stack ESP32 PSRAM Timer Camera
• 4 x M2x10mm Hex Socket Countersunk Screw
• 1 x M3 Square Nut
• 1 x M3x8mm Hex Socket Cap Head Screw

For the last two fasteners you should have spares from your Prusa Enclosure build. I printed in Prusament Galaxy Black ASA. Any reasonably temperature resistant filament should be fine (it is installed inside the enclosure which gets quite warm).

After printing I reamed out the through holes on the bottom cover with a 2.1mm drill bit, very slowly since the posts on the inside can be fragile. You can then insert the M3 square nut into the pocket in the bottom cover, ensuring it is aligned with the hole on the back.

If you have an M2 tap, I found that it helps to start the first millimetre or two of the holes on the front cover with the tap. You can then put the front and back cover together and screw in the M2x10mm screws from the rear, threading them into the plastic on the front cover. Go slowly and do not overtighten, they only need to be tight enough to keep the front cover secured and the PCB pressed between the parts.

After assembly mount to the Prusa Enclosure through one of the unthreaded holes with the M3x8mm screw. I chose the front right 45 degree angled section to point the camera at the printer. I mounted it at the bottom since most of my printing is in the bottom half of the build volume.
