When you have glasses, like me, you can no longer stick a pencil behind your ear. Pencil Clip to the RESCUE!!! This clip slides onto the side of your glasses and grips for a secure hold. Then you would simple slide or snap your average sized pencil into the round holder and PRESTO! Now you can hold a pencil "behind your ear" without it falling out! This design is still a BETA because since I printed the first model, I have tweeked the design to be a bit more snug around the pencil, so be warned if you want to print it. Dimensions ::: The pencil holder was measured to fit all standard pencils. The clip is about a centimeter tall and about 1/2 centimeter wide. Download to see actual dimensions.
