This is a desktop pen stand for a Fisher Space Pen model 400 (The bullet one).
I wouldn't print it with support, just because the lattice will probably have supports in it and that would be a pain. You'll probably need to sand down some parts around the fins to get the pen to fit right, I just measured the dimensions and estimated, I couldn't scan my pen to make sure.
It does have my initials (FB) on the back of the tower, but that should be pretty easy to change; unless if you are another FB, in which case good for you!
It measures 4cm by 75cm by 90cm (1.5in by 3in by 3 3/4 in).
EDIT: If anybody has the time to take a scan, I'll fix the design to be precise.
