The Fixed Pen Cap

Many people have a issue about the their pen cap. If they lost the cap of their pen, the head of the pen will become danger and might hurt their skin. This 3D printed pen cap is able to replace the lost pen cap. I used the ruler to measure every inch of my pen cap. Then I used those information to make a copy of the pen cap. The pen cap was a little broken when I put it on my pen. So I should make it stronger or harder.
