Tracing Pen/Pencil Holder

Ever need to trace a 3D object onto paper but have a hard time holding the pen up at the right angle to trace around the object?

I made this pencil hold to do solve for that. I was trying to trace some things onto poster board so I can then cut them out of foam. This will accept any writing tool that is no more than 11mm in diameter.

Print upright with supports and 20% infill (could use 10).
