Mini Clipboard with Pen Holder

The mini clipboard holds half-letter-paper pages. The pen clip securely holds one 10mm-diameter pen, like Pilot Frixion, Pilot G-2, or Sharpie S-gel pens. 

To save paper, I use half-letter paper pages when working with students or writing quick notes. I'm sure you can buy 5.5"x8.5" paper (approximately 142mm x 216mm), but I simply cut letter paper in half (incredible, I know). BONUS – I attached my 5mm grid paper (PDF) that you can print and cut.

This model prints in two pieces, the clipboard base and the clip. I printed both parts in PLA with supports and a brim to help bed adhesion. 

The pen clip is a tight friction fit into the slot along the top of the clipboard. Glue is not required. Although, I suppose you could sand and use glue, if desired.
