3D printed sluice. Not my model
(vegantheoryclub.org)
There's uselessly tiny gem fragments in them thar ancient alluvial gravel beds.
Model is bought from: https://cults3d.com/en/3d-model/various/gold-sluice-box-v2-modular-expandible-included-4-mats-classifier although easy enough to design yourself. It works great though and the price is fair if you do want one.
Sluice body is petg, mats are tpu as I thought it would make cleaning easier. TBH petg would probably be a better candidate as long as you did a high contrast material. The flex doesn't add much as it's short sections that fit in a pan anyway.
I wanna see your findings.
Uh tiny fragments of zircon and saph I haven't sorted yet. A single flec of gold and a metric tonne of magnetite.
Gonna dry the cons and strip out the magnetite and look for more gold, it's not an area where you expect it though. This was the sand from classifying a few buckets for sapphire. Photo of sieve finds attached, the sluice found similar stuff but smaller.
Very cool, thank you.
The sluiced fragments (some of) hairtie for scale.
Not practical, but I want a tiny 3d printed chest of gem rough so for now I'm collecting it all.
