18mm to 16mm screw diameter adapter for 8X zoom lens

thingiverse

I made this adapter that lets my friend screw on an 8x zoom lens with his phone case. However, I noticed that the screw was too small, which created a problem. To fix this issue, I came up with a solution by creating this adapter that allows it to screw in perfectly. It's designed as an 18mm female to 16mm male connection. When printing out this part, you may need to adjust your settings, since the quality can vary depending on your printer model. This is because it's a small component that requires some precision.
