Summary

This is the second version of the hopper, Improvements include:

Second punch plate
automatic feeding hopper (uses water)
less plastic needed

This should function extremely well when gold hunting, the punch plates were also designed after the ones in ¨Gold Rush; Freddy Dodges mine Rescue¨
Once all parts are completed, you will have to glue the hopper securely to the spray bar, otherwise, the water will leak out of the sides, and the automatic feeder will not work.
IMPORTANT: When printing use SUPPORT ONLY TOUCHING BUILD PLATE you will otherwise never be able to remove it from the spray bars, and pipes that run along the inside. Please let me know if there are any problems with the design, or if you have suggestions for future versions. Comment if you would like a mark 3 at some point.
