A couple more renders on the aperture project

After a few prototypes, I've discovered that a few modifications were required.  The bolt head is now shaped for a pan head bolt (much easier to find) and slides in from the back so that the archer's view is smooth and symmetrical.  A few parts were thickened to add strength, and a few places were trimmed to avoid thin wall problems.  Also, the third variant, the non-glass o-ring only aperture, was added.  All will be available in right hand or left hand.
