Universal LED Light holder

This is a super cheap method of adding light to any 3D printer that uses the standard 20 mm square extruded aluminum frame, fits on both 20 mm v-slot and t-slot extrusions. It use an ultra cheap set of LED strips and any AC to DC converter delivering 12-15 volts. Each hanger uses about 50 grams of material, I recommend using PETG or ABS+ to minimize deformation in a heated enclosure.

The LEDs come in a 6 pack for $8.88, each hanger accepts a single light, you can use the adhesive strip or hot glue to install the LED in the hanger. Each strip cost less than a $1.50 per LED and they are super useful to have.
