• To be able to place the gears in between the structure you will need to print the structure first and mount it on the motor box.
• The motor box is the main pillar, holding the structure together.
• You will need 2 mm diameter rods (as seen in the video).
• This is one of my first designs, I am sure there are lots of points of improvement. However, as-is, it is easy to print and assemble (if you have the rods, and a hot glue).
• It makes quite a lot of noise, because the bedding/bearing of the gears are quite primitive. This is a point for improvement.
• I designed the gears on rushgears website, downloaded STL file and merged / adjusted for the final use.
