Traxxas X-Maxx center shaft cover

thingiverse

So, the X-Maxx spur and pinion are steel. This means they need to be lubricated, but they run dry. If you want to fix that, the problem is the hole at the bottom where the center driveshaft goes. Thus I made this little part that's supposed to sit down there glued with silicone and close that hole. Unfortunately, since there isn't much space it doesn't fit with stck 54t (big) spur. It surely fits with 46t spur and most likely will with 50t one. Then you can put grease in there. Manual transmission oil should work even better - the RPMs those gears work with require oil, not grease. This will need it all sealed it all around with silicone. I've printed it but hadn't installed it yet, I need a new spur.
