This is a great and fast way to test for gold passing though the Goldbox XL because the settings were off a little

"I don't want to see gold" tailing sluice STL file

This is the 1st revision and not perfected (that’s why its free). But as is so far it worked well with either a 500 gph or 750 gph pump. (Inlet hole diameter is for 1” or smaller OD hose)

If printed with logo side down on the print bed, no supports are need to print it.

Also its design to fit on to a sluice with an indicating mat, so for it to clip on and stay in place the total thickness needs to be 3/16 or a little thicker.

The locking clamp for the hose will take a 10-32 size screw and nut or smaller.

I would recommend printing with PETG filament for strength and a little flex on the clamping arm. Always print with a 4 layer wall thickness min, to prevent water seeping out of the walls
