Small DC motor gearbox 186:1

This is my small 3D printed gearbox 186:1 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.This design is replacement for this motor https://pl.aliexpress.com/item/2-sztuk-TT-silnik-130-silnik-samoch-d-zdalnie-sterowany-motoreduktor-dla-Arduino-DC3V-6V-DC/32868653773.html?spm=a2g17.search0104.3.28.59de2441ls7byg&ws_ab_test=searchweb0_0%2Csearchweb201602_4_10065_10068_10843_319_10059_10884_317_10887_10696_321_322_453_10084_454_10083_10103_10618_10304_10307_10820_10301_10821_537_536%2Csearchweb201603_51%2CppcSwitch_0&algo_pvid=da30e378-d94a-426f-bcc1-916337732100&algo_expid=da30e378-d94a-426f-bcc1-916337732100-4 .To build it you will need all the 3D printed parts(2 spacers), motor and:

Hot glue (to glue the motor and motor gear)2x 3mm screws and 2x 3mm screw nut 2mm and 3mm drill (to drill holes for screws and drill trought gears)23.5mm x 2mm shaft 27mm or longer x 2mm shaftDremel tool to cut motor shaft if it is too long

*If something does not fit,use sandpaper

I will use this gearbox as drive 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 design more things
