Gearbox 186:1

cults3d

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 shaft Dremel 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.
