Notices for the lens build.

• Super glue causes discoloration within the lens and along its key surfaces. Have black paint on hand to conceal these.
• Pegs are needed to facilitate the movement of the focus mechanism. Simply cut three 7mm pieces of filament and glue. These should allow for smooth movement.
• Not all black PLA is created equal. Find the best material at https://www.thingiverse.com/thing:1662956
• Use high-detail print settings.
• Any warping may result in looseness around the aperture. This can be rectified with an auxiliary flange.
• Depending on your aperture assembly technique, the control ring may not fit. Reorganize the blades or slice the model to create a secondary flange.
