This is a model of a WWII Boeing B-29 Superfortress Control Yoke. How cool will this be to print full-size and hang it on the shop wall? Thats what I'm gonna do, and now YOU can too! A resourceful sort could even print this as a shell to go over a sturdy steel steering wheel and use it in a old school hot rod. I found this bad ass thing over on Tinkercad, and the original designer said build it! Share it! The original can be found here :

Also, that dude has many other cool designs, some of the best I've seen over there so far..
There were a few variations with these yokes back when the planes were originally built because of the number of manufacturers involved in the war effort. This leaves room for remixes on the yoke cap and other details. Read about that, and B-29's in general at the following links :
