transfer case (test1)

this is my first rough draft attempt at 3d modeling a transfer case for a scx24 rc dirt crawler model i am trying to 3d print as much as possible of the build... its in rough shape and will possibly break in real world conditions. i printed it, cleaned up the supports, sanded the parts a little, oiled it and got it to spin with my fingers. it needs the drive shaft adapted and probably bearings in there somewhere. if you have an suggestions or want to help redesign it or something, let me know!
