When I started working with gears then always was a problem, how to connect them to the shaft efficiently. Here are 4 different ways how to attach them to a rotating shaft.

I hope this video is helpful and u find out new and great ideas for next time when u are working with any project where u have to use 3D printed gear / gears.

U have to remember that 3D printed gears are different than metal gears, that's why there have to be new ways that are reliable with plastic.

I wish u luck for next time when u 3D print gears and hope u use some ideas form this video! ;)
