This is a hex tile with 3 different height risers, hexes can be glued or slotted into the risers giving you the ability to create more elaborate obstacles.  You will need to print the hex base, the stabilizer, riser pegs, and one of the pairs of risers, it's all modular so you can pick the height you want and swap it to a different one later or just print more.  

The tall riser is 230mm  (includes the base hex and top hex so 222+8 for the two hexes)
The medium riser is 164.5mm
The short riser is 107mm

I shipped off the prototypes (before getting pictures, whoops) for outside testing but have a new set printing to decide if I have any other changes I'd like to make.  I'm working on ramps and bridges using these tiles as well.
