Thanks to sculpteo s online services you can design your own custom gears in many materials with both 3d printing and laser cutting.
The first problem faced was when producing gears.
Each wild gears product is called a gear set and is laser cut from a solid sheet of acrylic.
Gears with a laser cutter even the complex profiles of involute gears are easy to cut once you have a vector drawing for the gears you want to create.
The gears in question are cut out of mdf board which is readily usable on all but the feeblest lasercutters you ll find in the average makerspace.

The first laser cut is made as close to one end as possible.
Wild gears are the end result of a kickstarter campaign that set out to make a newer better spirograph like product.
I need to keep the gears as light as possible without losing much from the accuracy i do have relatively small gears i m using a tooth size of.
I am not familiar with laser rental rates but actual laser time to make each cut of an acrylic rod is no more than a few seconds.
Each piece feels good solid crisp.
