This is my first real electronics build with no prior CAD or wiring experience, so it took a lot of trial, error, and effort.
Everything you need to print, assemble, and light up is right here.
Assembly
Just print the parts and put it together. I used M2 screws for mounting.
A blank enclosure model is included if you want to reuse the box for storage or your own mods.
The box fits almost everything except the LED, with plenty of room to spare.
Inside the lightBase model, you’ll find two 4 mm holes for M2 screws to mount the LED starboard.
Lighting Setup
The light uses a 1 W LED mounted on a small heatsink.
Brightness control is handled by two resistors for Hi/Lo modes:
4.7 Ω – High brightness
10 Ω – Low brightness
An optional bypass button gives instant power, based on if hi/lo is selected to the LED. (Check the Tinkercad wiring diagram for reference.)
