Extendable trays

thingiverse

While ago I created these trays. They stack using posts either up or sideways. I've used them for years and they work incredibly well. Posts come in two printable configurations: vertical and horizontal. Choose the one that suits you best; I opted for vertical. I included two inner trays to demonstrate what you can create on your own. Clearly, I won't be making inner trays with multiple configurations, so you'll need to take care of that yourself to meet your personal needs.
