3D mini marble game device

This is a 3D printed mini marble game device, also known as a 'marble scam' demonstration model.

Materials needed

Bambu Lab starter kit

       8mm stainless steel marble-------1

       0.5*5*25 compression spring-------1

Its structure and gameplay are as follows:

- Main body: A white 3D printed casing with score zones marked '0 3 0 2 1'
- Launch mechanism: A spring and plunger on the right side, used to launch the metal marble
- In a street 'marble scam', by controlling the tilt angle of the device or hidden internal mechanisms, the vendor can manipulate where the marble lands, making it nearly impossible for players to score high and thus swindling money

In essence, it is both an amusing desktop toy and an educational model for demonstrating and exposing street scams.
