Build your own chain of gears with this simple gear and link system! Make each gear any color or pattern, use your slicer to paint them or put letters on them, make it as long as you want!
Only four parts are needed to create any length of gear chain. Start with a Linkage End piece and put as many key gears attached to lock gears into linkages as you want - then end with another Linkage End piece to finish the fidget! See picture for a visualization.
Notes:
There are two patterned gears included in the files - one is a caterpillar face, the other a spiral
There are two linkage dimensions included. The "tight" file will keep the chain stiff, while the "loose" file will allow the chain to wiggle and turn (see gif for example)
Gears are designed to be snap fit - once they are squeezed together, it may be difficult to get them back apart without breaking them
Not all filament is printed the same - if the key gear doesn't fit well into the lock gear, try to scale the key gear +/- 1% until the snap fit works. Alternatively, if the key gear is too small and the gears are falling apart, use superglue to secure the gears in place.
