It looks like I need to cut the wheel well farther forward or cut new sliders to get within 1/2" of the wheel well for metal slider points.

Next on the list is a full interior, paint and finally testing. I should have it done in the next week or so, plenty of time to get used to it before the next scale comp in April.
 
Cool build, I don't really understand all the classes and stuff yet. How can I learn more about this 3d printed transmission and transfer case?
 
Sweet looking build!"thumbsup" A lot of cool stuff going on here!8)

Following to see more!:)
 
Definitely following along on this one. I really like the XR width axles. I have a soft spot for 2.2. Very cool build!

Oh so it's just the housing, thats more in line with what I've been seeing. How does the 3dp housing change your setup? Is it an orientation thing or a weight thing or something else?

All of the above. Moves the motor forward and down from a stock 3 gear trans and allows for a full interior as well. Lower Center of Gravity, more forward weight and the motor on the drivers side helps counter torque twist.
 
Got enough done it was time to get out and test. This is with no additional weight aside from the brass brake drums up front and the brass tubes in the front axle. I think I need to go up in spring rates, it feels a little sloppy on off camber climbs. Otherwise it feels really good for a new build and it should only get better as the tires break in and I get the shocks dialed in.
