Small DC motor gearbox 15:1

This is my small 3D printed gearbox 15:1 for this motor https://botland.com.pl/en/dc-motors-without-gears/4721-mini-dc-motor-mt86-3-6v.html ,but I am pretty sure this will also work with diffrent motors with 2mm shaft diameter. To build it you will need all the 3D printed parts, motor and:

*Hot glue (to glue the motor and 12t gear)
*2x 3mm screws and 2x 3mm screw nut
*2mm and 3mm drill (to drill holes for screws and drill trought gears)
*16mm x 2mm shaft
*25mm or longer x 2mm shaft

I will use this gearbox for roller brush to my autonomus vaccum cleaner robot project and I will also try to upload diffrent types of this gearbox with diffrent ratio

If you like this project you can support me so I can project more things
