For a while I wanted to create this object from ingress game, so look on the internet and edit a model to return Printable.
In the large project resizes the lid so that it could be used as a type of container
This project is fully editable, when I printed it big as 0.5 mm
with 25% of infill
If you want a smaller capsule y recommend print al .2 mm I put 33% for infill.
