This is a project I've been kind of working on for my own hobbies of gold panning, in this project there comes 3 parts
1. The gold sluice box

2. The vortex sluice mat (based off of nimmermehr's design here)
3. The bottom of the box attachment (optional)

This is used for gold panning out river gravels, paydirt or anything of the sort and should all just slot together perfectly, the purpose of this project was to allow basically anyone who wants to get into gold panning/sluicing an ability to do so without needing to buy possibly hundreds of dollars in sluice equipment.

Setting up is very simple!
1. Print out as many sluice boxes you want (Object part 1 of 3), and the same amount of gold sluice mats you want (Object part 2 of 3).
2. Place the gold sluice mat into the box (Make sure the mat is placed in like the images above) and slot the little notch inside the box into the gold sluice mat
3. Stack them staggering, meaning rotate each box you print 180 degrees ontop of eachother so the flow goes over all the other mats on your sluice setup!
4. Completely optional, but feel free to print the bottom of the gold sluice box and attach it to the bottom of the whole setup if you wish.
