Nerf Rough Cut 2x4 Replacement Gearset

The gearset in the Nerf Rough Cut 2x4 is very susceptible to breaking off teeth when the priming grip is forced. I created a simple set of gears that prints at 100% infill and should take about an hour and fifteen minutes. If the center hole is too tight simply open it up a little with a 3/32inch drill bit. Also don't forget to give all the gear teeth surfaces a good helping of grease before you put it back together.
