Mobile phone place in the kitchen

Completion date: February 27, 2019

There is no place for me to put my phone anywhere in the kitchen. If there was it wasn't a safe place.

Gear investigation: Klutz Lego Blender

Completion Date: May 31, 2020 After I finished with Banbao gears collection, I search on web for other building instructions.
