connectable sluice box bottom

Print many of the same part and connect them all together to make a long bottom for your sluicebox!

UPDATE!

Now added another TWO new pieces to the puzzle!
And there will be more to come :)!
Though I have not tried to print the new ones yet so bare with me, you are free to try if you want to! :)

I realized the connection parts did not fit properly, made the old model in a hurry.
