Compact Insulin Pen Case (KwikPen / FlexTouch)

Description:

Credits to datageekau for their original work. I was looking for a compact insulin pen case that could fit into my Mous Extreme Commuter Tech Pouch and other small everyday carry bags. Most options I saw were much larger, so this seemed like a better fit for my needs. I also really liked that Datageekau's design allowed for a pen needle to also be stored safely. However, their original design had some structural flaws that caused a breakage while screwing it closed, so I wanted to make some revisions that would make a sturdier design.

Changes:

Note that I created this from scratch using TinkerCAD, although I could have used other software to create higher resolution models.

1. The Insulin Pen Tube container now has threading on the inside of the tube, as the original design with external threading was very thin and easy to break. And when it did eventually break, you'd have to re-print the entire tube which would be a lot of filament.
2. The Needle Holder Cap screws into the Insulin Pen Tube to secure the Pen, the threading is hollow which allows the Pen Needle to rest inside this piece. If for some reason the threading breaks, re-printing this piece requires much less filament + time compared to re-printing the tube.
3. The Cap functions as the cap for either the Needle Holder or the Insulin Pen Tube so it can be used for just the Insulin Pen or for the full kit with a single Pen Needle.
