Metric Ruler for Keychains

Description

For Those Nerdy Times When You Want To Do Some Rough Cad On The Bus Without Calipers... Inspired By Tecaccessories.Com/Centipede, I Wanted Something With 1Mm Accuracy, Cheaper Than $22, And To Design It Myself. I'D Love A Real Centipede, In Case Anyone Is Looking For A Birthday Gift For Me (Coming Up In October!). Send Suggestions For Improvements! Update 2016-10-08 ----------------------- I Uploaded A New Hexagonal Version Which I Think Is The Best One Yet. Much Stronger, Easier To Print, Just As Functional.
