The rack turned out really well and there have been some comments that you may or may not take in consideation. I would like to add a couple and they are strickly just an opinion and I incorporated them in when making one for myself. I did not like the hole idea because a person has to constanly take the pen in and out of the hole with the possibility of scratching. The next thing was yes they may be safer from tipping if someone turns the turntable really quick but while i am watching that will not happen. Next with the half holes such as I have I feel you get to see the pen in its entirety and is easy to pick off and place back. Anyway this was my rack and if any of the ideas help feel free to use them. Good luck and thanks for showing.
