This pen holder is a two parts print with the container taking 7 hours and the lid 3 hours with fast print settings (with my old Tevo Tornado 3D printer).
Here is a short video of the resealable pen holder.

The lid opens and becomes a second container for the smaller stationery pieces.
The lid has two little bulges that keep it from unwanted opening when in the closure position.
