Modular Screw Organizer

I wanted a screw organizer that was expandable so as to prevent it from always being a fixed size– which is usually too large for my needs anyhow. This provides a 48mm×48mm dish for small screws or other parts– or anything, really. There's a spot at the bottom for a 5mm×2mm magnet, which is just enough to provide some gentle attraction to keep your screws from going all… screwy. No glue needed, the little connector pegs hold it well enough together. The clutch force isn't enough to paddle a canoe around, but it's reasonable enough for moving around.
