I’m not talking about computer memory.
I have a fair size collection of 1/4″ drive bits. Flat and phillips screwdrivers. Many sizes of Torx. Star drives, nut drives. But any way you cut it, sifting through them loose in a box was a mess.
It reached a critical point when I knocked the box off my tool chest and they scattered all over the garage floor. Colorful vocabulary and lots of searching on hands and knees ensued.
A quick FreeCAD design and some 3D printing later, and they’re all organized. Files are available on Thingiverse.
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.
Unfortunately, their manufacturing tolerances were way off. The shelves tilted downward into the room. A lot. The front edge of the shelf was about 2cm (almost an inch) lower than the back. Stuff on the shelves would work their way to the edge and then fall off.
