Evolution of Cube Gears

This evolution of my Cube Gears incorporates a new snap pin design, which is easier to insert, snaps more robustly, and prints more reliably. Included are plates for three different gear ratios (the ratios are the numbers in the filenames).

If you need the parts individually, you can export them using Customizer. You can also add custom embossed text to the large gears.

Instructions:

• Snap the pins into the center block first, then put the gears on.
• Sometimes the inside of the hole in the gears is weak; if you print with low infill, the pin can break through if inserted into the gear first.
• Apply some grease to the pins for easier insertion and removal and to ensure smooth rotation without squeaking.

Only the pins are interchangeable between the different ratio cubes; they all have different center blocks. The larger gears go on the larger faces of the center blocks. I print these at MakerWare's medium default settings in PLA. Support is not necessary.
