Mazzer Mini Grinder Mod

I need a 3D-printed part to replace the coffee doser on a Mazzer Mini commercial coffee grinder for home use. A similar file exists for a slightly larger grinder, but I need it scaled down and fitted correctly.

Requirements:
- 3D model in STL format
- Scale down existing design
- Ensure correct fit using existing part as reference

Ideal Skills & Experience:
- Proficiency in 3D modeling and printing
- Experience with coffee grinder modifications
- Attention to detail for precise fitting
