A circular spiral storage funnel.

Using this round screw funnel, you can easily pour screws into the corresponding storage boxes. If you're sorting screws, you'll need different sizes and several models.Use Sliccer to adjust the model sizeAnd it will suit the size and quantity of the screws. The diameter of the filling model is 60 mm, and the other one is 60 mm and 100 mm.

Use a very clean plateDue to the insufficient adhesion, I recommend using boards with good adhesion, such as textured PEI or PEI boards.
