Eureka Mignon (Basic) Tamper Support

Tamper Support (57-58mm) for the Eureka Mignon Grinder Basic version and others using the same coffee hopper.
I didn't put a hole for the hopper's screw as I don't use one, also it would depend if you place the tamper on the right or on the left.
There is a complete version and a 2 parts one if you like to avoid supports and/or save time.
