Got tired of never finding sticky notes and a pen to write on them at the same time in the same room, so I designed and printed this!

IMPORTANT NOTE: this was designed with this Muji gel pen (9.4mm in diameter) in mind, so it has the best fit with as little wiggle as possible. It also works with the classic Bic pen, but it's not as snug, and has quite a lot of wiggling. (I don't claim that this is a universal pen holder)

Pens that are more than 9.4mm in diameter (like most retractable click pens) will not fit properly. The pen holder contains 2cm of the pen.

On the sticky notes side, this holder is for classic square ones, and the square hole's side are all 7.7cm.

2nd note: the wave pattern on the side picture is purely visual, it's a flat side withtout anything special.
