This part helps me monitor my 3D Printer which keeps buzzing away in the dark, at a safe distance from living areas since it emits some unhealthy fumes…

I used components from a broken LED Flash Light, and a Lithium Ion Charger circuit that you can buy for a few cents.

The Lithium Ion charger circuit in this case is working as a voltage converter from 5V supply off of the Wyze Cam to the required 3.6V for the Flash Light.

You will need / BOM:

• TP4056 1A Lithium Battery Charging Board with Micro USB
• Cree XM-L T6 LED Chip
• Cree XM-L T6 LED Driver
• Reflector - Note - if your reflector is not exactly like mine - a minor design change might be required. Please just use some negative space to curve out accordingly

There are other ways of doing this obviously, but these were the components I had on hand.

I used mouse ears to stop the print from warping as PETG warps a LOT when printing items like this with pointed corners.

Brims just doesn't cut it.

The mouse ears are thick for that reason.

You will just need to cut them off with a pair of scissors.

I attached a screenshot of the print settings for best results.

Notes:

• I also uploaded an STL design for covering the hole - but personally I didn't find it necessary because it stays hidden by the Wyze Cam anyways.
   
• Also, notice that instead of splitting the 24V supply from Ender 3 Pro's power supply, and adding a buck convertor to it (popular way), I have just drawn 5V supply for the Wyze Cam directly from the Creality Board. Now, yes, there are risks in doing this, and please don't do this if you are not willing to take the risk - but my math was, it looked like the board can handle upto a total of 3 amperes and the Wyze Cam uses a max of about 240mA…
  And then there is the flashlight which is current regulated by the Li Ion charging circuit.
  So, I was not too worried about the board burning on me. But again - at your own risk, and the safest way I guess, is using a buck convertor from the 24V supply.
   
• The product from Wyze is a great option too. I just utilized the materials at hand, and didn't want to wait for shipping: https://wyze.com/wyze-cam-v3-spotlight.html
