Specification

Take the station apart.

Every part is a class we source, wire and test before the station ships. Select a part in the drawing or a row of the sheet and the other follows. Switch on Dimensions to measure it.

Station assembly

Select a part to read what it does. Pull the station apart to see how it fits together.
