Camera dolly for camera / gopro / Insta360

Hello everyone, this is my first COMPLEX design and i feel very satisfy of it !
Made completely from fusion 360 my original design except for one part : bearing by_DrMcWoofies (thank you , i love your project !!!) !!

I designed it so that you will NOT NEED ANY SUPPORT ! i don't like to waste money/time/material on supports and so i made several little items that can be easily connected one to another !
This little camera dolly will allow to make some cool smooth horizontal camera movements!
Beside PLA(or petg) you will need TPU to print tyres , 2 M5 bolts and 2 GoPro 1/4-20″ Adapter one for the top of the dolly and one for the bottom where you can plu your selfie stick !
