Inserting the pins into the center hub of the screwless gear cube and heart were kind of a pain in the fingers. This tool makes assembly much easier.


Use the end marked long for the long pins and the side marked short for the short pins. Very complicated I know.

Be sure to print it with enough infill to keep the pins from poking through the face at the end of the opening.

Thanks, very useful!

That is a great idea, I'm going to have to try this.

Thanks emmett. Your gear heart and cubes are always a big hit.

So it's not just me that thought those pins were a pain. Excellent tool!

This might even work better than the pliers I've been using.

Scaling it down should work for the smaller pins. If not let me know what size they are.

They are the same size pins as in my snake thing:
