This little widget will hold a 35mm slide against up against the light on the back of your laptop, if it has one. Then the light shines through the slide, and now you have art.
use some adhesive, or double-sided sticky tape to hold the three thicker tabs onto the laptop, leaving the open end facing up.
The open end has a little nub so the slide sticks in place.
It's a snug fit, you may need to make adjustments.
This works with thinner 35mm slides, I've seen some (metal mounts) that are too thick to fit.
I've printed this on a Cubify Cube printer, and the 3D Touch printer from 3D Systems. .25mm resolution.
Created in Tinkercad, with great amounts of help from Kacie Hultgren.
