MOAB - Parametric bellows and dosing cup combo for the Eureka Mignon

MOAB - Mother of all Bellows or Massive Ordnance Air Blast:

A bellows and dosing cup combo designed for the Eureka Mignon grinders.

Designed by Amahoola and me.

Demo Video:

Features:

• Functions as dosing cup AND bellows, at the same time!
• Drops all the beans at the same time
• Gives the possibility to run the grinder before dropping the beans
• Prevents some extreme popcorning by closing the hopper
• Parametric file available for editing to suit your needs
• Adds convenience to your workflow!

Notes:

• To print: Print a version of the bellows, the descriptions are written below, if you're not sure which one to get, just get the normal v1's.
• Everything is printable without supports.
• The bellows should obviously be printed from TPU, or something else that's flexible. The one in the video and pictures is printed with 91A TPU.
• There is a ring connecting the bellows to the insert, so the insert doesn't fall out. Connecting them can be a bit finicky, there is a version without the ring.
• The text might difficult to print for some or you might not want it, a version without it is available.
