Perhaps better known for Tetris, Robocop, Predator, Michael Jordan in Flight and other video games in the 80's and 90's, I have also designed 3D graphic engines, aircraft avionics and aircraft navigational training systems .

For 3D printing, I lean towards designs that are the easiest to print, hence my snap / slide / press / glue together designs.

Now retired, I enjoy keeping up with current technology, like the Replicator 2.
