About this 3D model

A bowl for the precise rinsing of gold and other sand minerals as a hobby. The bowl works on the principle of a whirlpool. In the grooves, heavier particles of minerals such as gold, sapphires and rubies are deposited. The rest of the lighter material flows through the center opening. The bowl has been optimized, printed and tested. It works and captures the minerals we care about. Best for trapping material with a diameter of 3 mm. Then it will retain the smallest particles. Material with a larger diameter can be sorted. Then you need to increase the water pressure and unfortunately you may lose some particles. But if we care about larger particles, it will certainly catch them. A very nice device designed and tested by me for an interesting hobby. Printed and tested, photos attached. Printed using the classic FDM method. Dimensions: Height: 110 mm Diameter / width: 185 mm Water connection diameter: 19 mm
