This is a revised version of the original model. Changes were made to the way the 2 halves are assembled. Now both halves have sturdy plates that join together to prevent the 4 top arms from bending. V2 makes the plates 2 times as thick. requires a marble no larger than 14.75mm.
After you insert your marble you will need to use 2 part epoxy to glue the two halves together.
The plastic version is heat sensitive so do not display under hot lights.
