Traxxas Spur Gear (for 2WD Traxxas cars)

thingiverse

Just recently I bought a new motor for my slash and I got one with a 5mm motor shaft, I didn't think much of this at the time but it really bit me in the rear end later on. Anyways I had to get a new pinion, but there aren't any 48p 5mm bore pinions, which meant I had to buy a different pitch pinion, which also means I had to buy a new spur gear to match, but there also isn't any traxxas spur gears for my car with bigger teeth (or aftermarket ones), so that is why I made this, It is a spur gear for the 2WD traxxas cars that have a clutch set up like what is in the 2WD slash. I have included the files for a toothless design (for you to make changes on, but try not to make the teeth too small because the pinion might rip through them) encase you don't have a mod1 pinion. I would also like to let you know, that these don't hold up to high temperature motors on warm days. I have experienced that on warm days (over 25 degrees Celsius) and when I have my 3800kv brushless motor on 3S going full speed (getting very hot and heating up the pinion) the teeth can start to melt. I have looked into higher temperature filaments, but I don't think they have the structural integrity that is needed for this case, which is why I recommend printing with PLA. I would also recommend printing a couple and just replacing them when they wear out. I would not recommend this this to replace an already working spur gear.
