Testing the 3D printed trigger system

A project log for The DIYson, an open source Cyclone vacuum cleaner

Why buying an expensive cyclone vacuum cleaner when you can build yourself one?

Pulling the trigger rotates the trimmer on the servo tester. The gears ratio has been designed so that pulling the trigger (a movement of about 25mm) is converted into 270 degrees of rotation of the trimmer.

To get it work on first try, I measured the PCB and size of all the components of the servo tester. Then I created a 3d model in Solidworks of the servo tester. I downloaded the Step files of some gears with the correct ratio from SDP/SI, then modified them to fit.
