Build the suspension (83Mb zip file download)

Alibre Design was used to create and simulate a model of the Aeronaut Suspension and export STL part files for 3D printing. 

On the GEAR page it was explained that this new type of suspension uses a twin-pulley arrangement to ensure that the camera maintains a fixed angle with respect to the kite line; a taut line generally being a stable reference against which a camera can be aligned. To achieve this the suspension incorporates only two pivots, as opposed to the four in a Picavet, and does not need any strings hanging from the kite line. A pair of ‘Capstan Wraps’ provide a quick and secure method of attaching the suspension to the line, and are lighter than the variety of metal clips often used.

The suspension was made using carbon fibre tubing and parts printed in an Ultimaker 3 using Ultimaker’s Tough PLA filament. This material has a strength comparable to ABS which you could use as an alternative (though smelly!) material.

Some of the pictures from the build file are reproduced here.

A full list of the materials needed, STL files and construction notes can be downloaded in the ZIP file here. However, if you don’t actually want to build this novel suspension then why not examine the parts using ModuleWorks STL Viewer?
