Simple bed worklights so you can see. Light are hidden behind the shell for a clean look and to allow for diffusion of the light.

The lights are connected to my heater 12 V supply. Std. 20 ma LEDs in bundles of four. The cover can be printed at scale and sanded to create a "snap fit"; or you can print it undersized and glue. I recommend snap fit as you can re-open the cavity if required.

These were printed in std. white PLA to allow for light diffusion.

I used a simple MT3608 to provide the voltage regulation; else you will get dimming when the bed heater cycles.

I created an inline box for the MT3608. It snaps in with a similar snap fit cover.
