Money counter (US dollar)

thingiverse

If you're visually impaired and need to identify a coin in your hand, slide it upwards until it stops, then feel the side for its value (US coins ranging from $0.01 to $1.00). Note that this is just a prototype demonstrating 3D modeling capabilities; it's not specifically designed for field use. Feel free to modify the design if needed, and remember it's an A8-sized tool.
