Shopsmith Mark V Bandsaw Coupler

I acquired an older model Shopsmith Mark V for next to nothing from a lady while on a service call. Several pieces were missing, one such piece being the coupler that connects the motor to the bandsaw. Shopsmith sells this adapter for $32, but I'd rather make something than buy it if I'm able. As you can see, my first coupler was made out of PVC pipe and epoxy. I've been using that coupler for over two years now with no trouble. Now that I have a 3d printer, though... why not print a new one?
