Everyday Carry Folding Credit Card Pen!

prusaprinters

<p>Small but Mighty! This credit card pen has pre-determined cuts that allow you to fold and lock in place to create a pen housing with comfortable grip. This pen is also retractable with no spring required! Simply pull the tab and twist to lock pen in place, and manually press the pen tip in to retract. This is V1 of this pen design with new improvements/additions on the way! Wanted to make sure I uploaded this on time to compete in the pen design contest :)</p><p>Note: This design fits standard ink cartridges (up to 3.4mm in diameter) but is designed to fit smaller cartridges in length (about 65mm in length). I was able to cut a full-length cartridge in half (that was almost empty) no problem!</p>
