Overhead Models

The moveable and transparent overhead models are made of three millimetre thick acrylic glass and are bolted with zinc-plated M3 screws and washers to give you years of pleasure.

They make it possible to represent complex interrelationships in running movements in a simple way. The base plate of our models is 300 x 300 x 3 mm in size.
