This was my first attempt at a small, self contained, recirculating gold sluice. Was mainly designed as a proof of concept. It works.
Completely self contained, runs on 4 AA batteries, and packs (almost) completely into itself for transport.
I decided to also include the mounts that allow this to be mounted on the top of a 5 gallon bucket, like you'd get from the hardware store. In that case, you wouldn't need the square base, or its parts, everything else fits into the bottom support, and the pumps dangle into the water. It'll make sense, trust me.
I really need to do a proper video on it, but at the moment I'm a bit short on time.

A little more about it:

Parts should already be oriented how they should be printed. Use your best judgment when adding in the necessary supports. Depending on your printers tuning, you may need more or less than I did.
Yes, there are a lot of parts. It was my first design! My second revision, which I will upload here after I get this one published, is MUCH easier! FAR FEWER PARTS!
