I designed this with Fusion 360, ensuring an accuracy of roughly half a millimeter. Add-ons: [linear drive conversion](https://www.thingiverse.com/thing:3107269) The materials you'll need include: 1 motor from a CD drive or similar device 1 adapter for the power supply (3-12V works well) something to secure the gears in place, such as 1mm and 2mm thick pieces of solder a belt, like the rubber band I used from my mom's kitchen Due to the significant air space within the wheels, there may be considerable resonance issues, resulting in a potentially noisy operation. It is highly recommended that you apply lubricant and possibly use a file to improve the tolerance. Assembly: superglue all components together as shown in the pictures. Note for printing: turn the base as depicted; attempting to print it any other way would pose significant challenges.
