About this 3D model
This pen body was designed to add an interesting geometric flair to an otherwise ordinary pen. The part was designed to fit the ink refill from the Bic Cristal pens, which can be found here: http://amzn.to/2lndAQm When I first designed this I printed mine horizontally (with several small supports), but it can also be printed vertically (point-end down). In that case you may want a brim.
