Hexagonal Ring Module for GraviTrax-Compatible Tiles

WHAT THIS IS: This is not a standalone part. This a module to easily integrate the ultimate embedded hex mounting ring into your 3D GraviTrax marble run accessory designs. 3D designs for GraviTrax marble run accessories need better hex mounting rings, and this design is the best I have found for a number of reasons. HOW IT WORKS: The base ring is embedded in the base. Use tweezers to pull it out and then turn it 30 degrees and snap it back in. Video showing this at https://www.facebook.com/17188
