The Cheapest Led DIY Module Ever

I hope my thoughts can be understood by you.

I hope my thoughts can be understood by you. The Led module has an external threaded diameter of M50*4*10, installed in the lampshade you designed. You only need to draw a circle with a diameter of 50.6mm. Using 50.6mm instead of 50mm is a tolerance added after testing. Add M50 to the drawn circle, a pitch of 4, and a length of 10 threads. I used Fusion 360 to draw the threads.

The cover diameter of the fixed Led light board is M40, which retains the tolerance in the design, and can be printed directly, which can better fix the light group.

It uses a UsbC module and is powered by 5V. I bought it with few money, and it was very cheap.

When installing, it is better to place a few drops of 502 at the fixed place of the USB port.
