Coin trap

Hello

Here is my 1€ coin trap It is a spatial maze requiring 3D visualization and memory

Once the coin is inserted, it no longer exits through the entrance You then need to perform manipulations to follow the path to the exit! The path is designed so that the coin moves backward more easily than it moves forward when you haphazardly move it The piece is designed to have no supports that could not be removed from the inside and its printing with a Bambulab X1C works perfectly

Print and show the 3D cavity (available on the plate, but requires a lot of supports) For example, give the person one minute to learn the shape of the cavity, then let them get the coin out!

It is good practice for spatial geometry, 3D visualization and memory

Find a video showing how to get the coin out on my website here

Happy printing!

A few details to help get the coin out

Insertion hole: The one of the two that is rounded on the edges

Initial position:
- Insertion hole face upwards
- Hole facing user
- Hole direction front/back
- And therefore, hole on the left side

Axis definition relative to the user:
- V = vertical
- Haa = horizontal front/back (right or left rotation)
- Hgd = horizontal left/right (front or back rotation)

Instructions:
- Insert the coin
- Tilt Hav 45° to the right
- Shake a little
- Turn Hgd 3/4 back
- Shake a little
- Turn Hgd 1/2 forward
- Shake a little
- Turn Hgd 1/2 back
- Shake a little
- Turn Hgd 1/2 forward
- Shake a little
- Turn Hgd 1/4 forward
It falls into the cavity
- Return the box to its initial position
- Turn Hgd 1/2 forward
- Turn Haa 1/4 left
- Shake a little
- Tilt slightly to the left
- Shake a little
- Turn Haa 1/4 right
- Turn Hgd 1/4 forward
