I searched for a long time for a compact method to store my collection of thru-hole resistors. Finally decided to design my own box. This is an extendable design where you can stack trays on top of each other, each one seals the one below it, and one lid seals the top one.

The included STLs define a tray with 10 cells, 10x10x70 mm each (about 20-25 1/4 watt resistors).

Feedback is welcome, as I'll probably attempt to continue improve the design. Tips keep the motivation... :)

Enjoy! Gilad.
