Pen Carrier

thingiverse

Problem: Needed a way to easily carry from 1 to 7 writing instruments along with my engineering design journal. My favorite journals for use in design journals and bullet journaling are the Leuchtturm Medium and Large journals, but they can only hold one pen if I purchase the separate pen loop. Solution: Design and print out a pen carrier that clips onto the cover of the journal and holds between 1 and 7 writing instruments depending on how much I want to customize it. Design Criteria: The carrier must securely fit a wide variety of pens. (From thin mechanical pencils up to the diameter of popular Pilot G2 size pens.) The carrier must fit on the cover of the Leuchtturm Medium journal (or equivalent thicker covered journals). The carrier must be easily removable so another unit quantity carrier can replace it. NOTES: The design was created in Autodesk Inventor in INCH format. If your slicer imports the model very small, it is most likely importing in as metric by default. You will need to scale up 25.4 times to get the same scale in Inches. Print the design on its side on a raft for best surface finish. Support material should not be needed. Pens I love that were tested and fit: Sharpie Pen (Thinner Capped Version NOT Thicker Click Version), UniBall Signo RT, Faber-Castell PITT Artist Pen, Foray Advanced Ink Needle Tip BallPoint, Pilot G2. The largest diameter I would comfortably go is the Pilot G2. The Leuchtturm Medium journal cover thickness is approximately 0.083 inches or 2.11mm.
