rubber band gearbox, dc 130 motor, 1/81 gear ratio
Description
https://youtube.com/shorts/YM3BqX5QpPw?feature=share advantages: -quiet compared to gear wheels -no need for a metal shaft (some are hard to find, but if you want it to be stronger, you can put a 1mm nail in the middle of the columns where you attach the wheels) - compatible with dc 130 motor disadvantages: -may be easier to wear out due to friction -you may have a hard time finding the 20mm rubber band in the picture (these are my daughter's hairpins, you can double the rubber bands instead of these hairpins) **Print the base part as in the picture (using support), this way it will be more robust as longitudinal printing will be done) **gears 95% infill, 0.12 resolution **base 25% infill, 0.3 resolution **made with thinkercad
