I saw the other comment about different length screwdrivers. I measured mine and scaled up the height on my print. The drivers fit very well.
I looked at the option of shortening the shafts, but mine had a flat spot ground to accept the 2mm set screw. I did not want to grind another flat, so I left them at the stock height. Thankfully, this design was flexible enough to accept re-scaling well.
