This is my infinity gearbox. You can pick and choose what types of gears you want to add to it, and assemble the modular parts to your hearts' content. It also includes parts that support adding a motor to it, so that you can use the super tiny Maker's Supply motor to lift super heavy objects.

Of the four plates contained in this model, the first one has parts that should only be printed if you're planning on adding the motor. Otherwise, just print two of model “End 2”, skipping “End 1” and all of the M1 gears (pinion, middle, bottom).

I've found that I can get about 5 gears in total before it becomes impossible to spin the fast way, so keep that in mind before you print a bunch of stackers. Additionally, the more force that is required to spin, the more important it is to use large module gears, as they can handle the additional stress. I'd recommend printing an M4 stacker or an M2.5 to M4 converter and start from there before you print too much of anything.

I have attached the Maker's Supply geared motor if you want to use the exact one, or you can get yourself a clone.

You'll also want to get some of these metal rods which the gears sit on.

Printing it in a fun, color-changing filament makes the model especially fun to play with.
