Another design was concocted which used the threaded rods to hold the eyepiece while still allowing movement. Hollow half-circles were used as springs to wedge under the lip of the viewer. The purpose was to allow the viewer to travel along the threaded rods while the printed pieces would keep it in place. If movement in another axis was necessary it would be done by repositioning the plastic which would attach to the glasses frames.
It took a couple tries to get the correct design and there were printer issues as well. Actually, lots of printer issues. A working design was finally made and movement across the threaded rods worked as expected. One key point was to use a thread tap, 4-40 in this case, to make sure the holes were able to accommodate the threaded rods.
Even though the eyepiece was capable of precise positioning, the design still didn't put the viewer where it needed to be. The printed pieces still go in the way too much but the metal and plastic look was pretty cool.
The rest of the posts for this project have been arranged by date.
