Lens Turbo II Canon FD Aperture Control Fix

Fixes a problem I had with my Zhongyi Lens Turbo II FD adapter where aperture control wasn't working on some lenses. This extends the little screw that's supposed to engage the aperture lever on the lens for more reliable contact. It also makes mounting lenses a little less fiddly. 

It fits snugly in my copy of the adapter, but you may want to add a drop of superglue to keep it in place.

I printed with .12mm layer height and 100% infill.
