About this 3D model

Here is a gear that can only be made by a 3D printer. It is impossible to take apart then put together this object. It is better to print it with a layer height of 100 microns but can also be made with 200 microns. The very first time, it will be a bit hard to make your gear rotate, but after, it will be alright. Free Filament - PLA - 1.75mm
