This is a stackable tray with a funnel at one end. As designed, it is approximately 210 x 147 x 30 mm, but I've been scaling these to 60% in Slic3r to print. I'm printing at 0.2 mm layer height in PLA.

These are great for just dumping a jumbled mess of small parts or hardware in to sort through, then pouring everything back in the bag or bin with the funnel, and since they're stackable you can keep them nice and orderly when not in use.

I hope you find these useful, and please link your makes and any remixes back here.
