3d printed pen holder

Your mission is to create a pen holder.

The measurements of the pen are:

153.23mm long

the cap is 8.5 mm across

the base at its widest is 6.75 mm across

add 2 mm to any measurement for a hole.

Make a design that will hold the pen and keep it from getting lost.  Use your imagination to design the object that will hold the pen.  The choice is yours.
