Polymer Clay Gears

Posted on July 29, 2026

I’ve seen people making polymer clay gears but never actually using them functionally. Mainly they are for steam punk projects and are decorative. But I couldn’t see why polymer clay gears wouldn’t work as real gears to make things move, so I gave it a go!

I’ve mentioned that I took an online course with Puppets in Prague and I really enjoyed it and so I took their advanced course this year. As part of that we had to come up with a project using gears. I remembered Rob Ives has a cool mouse machine project so I made his model in cardboard and then set about making a polymer clay version. I used the same mechanism but I changed a bit of construction due to using different materials and also changed the character to be a robot. He has hinges at his hip and shoulder so he can freely move – to get on with his busy work! The robot is driven by a crank and a pair of gears made from Kato Polyclay. You can see him in action below.

The piece of wood was a scrap piece I was using for testing but after a while I decided I liked the juxtaposition and kept it. There was quite a lot of adjustments to be made and I learnt a lot during the process.

I decided to play about with gears in some small projects – here is the first one – a mechanical brooch. It’s backed with magnets so I can store it on the fridge or in picture frame as kinetic wall art too. I love the verstaility polymer clay gives me for colour and decoration.


I use Kato polyclay which is much more rigid than a lot of the other brands available I haven’t tried gears with other brands yet. I imagine they will be fine for small gears – I will give it a try sometime and report back!
