THat is a great idea but did you see the designer's disclaimer? It reads....

If you print spur gears large enough they last for years. I'm using modulo 2.0 gears in PLA for a system that is powered by a NEMA23 motor. It will last for years. Another idea is to use TPU in place of the flex beams. Or better by far is a poured in polyurethane. Ir filling the space with silicone seal.
