The Sannce I21AG wireless camera is great on Duet Web Control but it is big and the remote pan & tilt capabilities are not needed for 3D print monitoring. It is also big - far bigger than necessary for 3D printing.
This is my solution to that - designed to fit onto my 3D printers (a large delta and a cartesian based on an I3 steel clone).
Strip down the Sannce camera, removing the two stepper motors and all but the front curved section that the camera is screwed to (by the way, both my camera boards only had 1 of the 3 board mounting screws attached - someone was too lazy to do the job properly!).
There is a recess in the back for the speaker and a bit of hot glue holds it securely. Two of the screws from the Sannce are used to hold the camera to the new backplate - the ones with flanges. You will need to drill 2 x 1.5mm holes in the white edges of the camera mounting bit for these screws.
The power cable is fed through the strain relief section before exiting through the hole and then being soldered to a suitable connector or power cable. I did not re-use the USB socket although you may choose to do so.
The WiFi antennae simply clips into the hole on the top of the new back.You will need to carefully remove the coax connector from the PCB and replace it afterwards.
3mm cap screws, washers and nuts are required.
Other parts designed for my printers include:
