An inclinometer is a devise used to measure the height of something that is too large to measure, I.E and tree or building.

Using the inclinometer you can measure the distance away from the object you are measuring and point the inclinometer at the top and read off the angle, using trigonometry to tell you the height.

An inclinometer is also used when making rockets to measure how high they reach in the sky

All of the inclinometer fits on the makerbot x2 replicator build plate and can be printed at 0.3mm low quality with no support or rafts.
