Here's a CAD file of the 6mm to 1/2" hex banebots adapters that I whipped up. Both in Creo and STEP flavors. Feel free to use however you want-- this is as close to the technical drawings as I think I can get.

This one is three wide, but I can make a 1 or 2 wide if you'd like. It's a real shame that it looks like BaneBots is going to stop selling these.

My brother managed to make one out of a piece of VEXPro Thunder Hex by drilling out the bore to 6mm on the drill press and drilling a hole in the side through which he tapped the threads for a set screw. It was pretty cool.

I thought about doing the same thing with the thunderhex. we did this last year with our FRC team to adapt a 10 turn pot to a shaft to track the height of our linear lift. worked out really great only instead of drilling and tapping a hole in it we cut a slit down it and used a shaft collar to lock it back together. we may have to see if we have a piece of thunderhex around and try this out.

thanks for the cad file. and the explanation of it. do you see any reason this wouldn't work with the #35 sprockets from vex pro?

#35 chain on a FTC robot?

I don't see a reason why it wouldn't work, but I'd probably go with a couple of the #25 sprockets instead of one of the #35 doubles. I'm pretty sure buying an adapter plus two of the VexPro sprockets is cheaper than getting a single sprockets from AM or Tetrix (although I suppose those have the advantage of just dropping in).

The biggest advantage of the AM sprocket is not having to rely on a set screw to transmit torque from the motor output shaft. AM found the slit + collar clamp method that IceStorm mentioned to be more reliable, which is what that sprocket operates on.
