Pen Case

myminifactory

I'm looking for a pen case that'll fit snugly into my backpack, putting an end to the constant search for missing pens. This design holds multiple pens with ease. Printed at 0.20mm resolution and made from PLA, it's off to a great start. However, I've noted that the top might be slightly loose, which is understandable given this is version 1.0. If anyone has suggestions on how to refine this design, please share your thoughts.
