I wanted to experiment with simple low-cost DC motors and see how easy it would be to make my own 3D designs to convert their high speed, low torque attributes into something more usable. So I designed this gear experiment set that lets you position and fix various gear sizes onto a matrix board. You can then drive the input with a commonly available DC motor or a crank handle option. I added a linear piston as an output device and also a spinning thing, but this is just a bit of a novelty.

The gears have various diameters; 50, 45, 40, 35, 30, 25, 20 and 15 mm
All of them have a 10mm inner spindle gear.
The 8 x 8 cm matrix boards have M3 holes space at 5mm.
Use M3 x 20mm screws to hold the gears in place. I did try printing some 3mm pins for this but they are not so easy to print and were too weak. You can also print the stand-off feet the raise up the matrix boards to give space underneath for any excess screw length or if you
