Sure-grip Sorting Tray / Deep Painters Palette

This model is inteded to sort beads/buttons/screws/whatever while being able to be gripped like a painters palette. Thus it is harder to slip from your hand while sorting.

It can also work as a deep palette with lots of room for paints.

All inside corners are rounded for easy items manipulation.

For printing I reccomend 2 walls, 10% infill, and concentric top/bottom shells.

The model is my own, but tray shape is heavily inspired by this model:
