Eyeglass Loop Mount Block

There won't be much call for this tiny print job but for those who need it...
Some time ago, I purchased the "Double Lens Loop" from Harbor Freight to assist me when work in very small projects. They don't appear to sell this device any longer but you can still get it in various locations on the Internet (amazon, ebay etc.). I quickly found out that they wouldn't clip to my readers because the frame was too thin. Today I printed a small block that allows the loop to attach easily and stay in place.
