Years ago, I bought a novelty gooseneck lamp for Joshua’s bedroom. It had four shades in primary colors (red, green, yellow, and blue if I recall correctly). It was fun, but the shades grew brittle with age and heat exposure and eventually broke. We redecorated Joshua’s room, and prepared to send the lamp for repurposing or recycling.
With a little design work, some glittery transparent PLA, and my 3D printer I was able to make some cool new shades. LED bulbs are cool enough that they won’t soften the shades, and the lamp has new life in the living room as accent lighting.
The shade design is on Thingiverse.
