Printing and Assembly:
Print the main body upside down (with arms pointing towards the ceiling) to minimize support. The handle prints upright, so you will have to remove a little support from the overhanging section on the bottom (of the handle).
Once the main body prints, be sure to “break loose” each arm and ensure that all the arms pivot and move smoothly. It helps to flush out any support material that is between the arms and the main body.
Once support material is removed from the handle and main body, then handle can be pressed into the top of the main body. You can use a little super glue or epoxy to fix the handle in place, if you like.
Note that when I scaled up the top by 2x, the handle was loose when pressed into the top. You need to use super glue or epoxy in this case.
