I am making a gear/cog to attach to a high torque stepper motor.
I can realistically make it out of the following variety of materials:
- 3D printer PLA/PLA+ etc.
- layered PLA/PLA+ and fiberglass made with high strength epoxy
- ply wood
- ply wood with fiberglass coatings
The easiest cheapest gear for me to make with my tools is made with PLA, and perhaps I can sandwich some casting epoxy with fiber filings mixed in to increase the width + exterior surfaces coated with a layer of fiberglass.
But since this is going into the core of a thing I am making on top of a "high torque" (the Nema 23) stepper motor, I would want the structure of it to last at least a little while, and the teeth not to grind themselves to grit.
What is the ideal path forward? (Going for customizability, cheapness, ability for me to make, and ability to interface with more fragile cogs and components further out from the main driving gear without tearing them apart).
