Summary
This is a remix of a very nice pen stand. I needed to make the hole larger to accommodate my 370Z pen so I enlarged the center hole to 13 mm in diameter (should be good for a variety of larger sized pens), and adjusted the model's inner wall since the larger hole initially removed too much material (i.e. the center hole was showing through the base).

I chose to print at 100% infill to give the stand as much weight as possible for my heavier pen. Overall, with these adjustments the stand came out perfect, works great, and has a modern stylish look.
