Frame clampable LED lamp. Warm white LEDs have a voltage drop of around 3V, meaning 4 of them are pretty perfect to connect in series across a standard 12V printer power supply.

Clamp to 2020 extrusion using my other clamp, 1x M5x10, 1x M5 hammer nut, 1x M3x20 and 1x M3 nut. There's a recess on one side of the arms for the lamp head for the M3 nut to fit.

Fit 4x 5mm warm white LEDs into the holes in the lamp (it's a really snug fit so you might need to push them in quite hard), and then bend and solder the legs together in series. Attach the two remaining legs to the 12V supply.

Printed in PLA. I expect other materials will work fine too. Use a neutral colour (white, black, grey), otherwise the colour of the light will be influenced by the reflections.
