Pen holder for books and calendars

This practical clip-on pen holder for your book solves a simple, yet annoying problem:

Where to put the pen?

I designed this part because I was tired of constantly buying expensive pen loops that either don't last long or simply cost unnecessary money. Instead, here you get a clever and customizable solution from a 3D printer.

The clip is simply attached to the book and holds your pen securely in place. No more searching, no more losing – your pen is always exactly where you need it.

By default, the holder is designed for pens with a diameter of 10 mm and books with a thickness of 1.8mm.

However, the design can be easily customized, so you can easily use pens between 5 mm and 15 mm in diameter and books of various thicknesses.

If the pen doesn't fit perfectly, either choose a slightly smaller diameter or wrap a bit of Scotch tape around the pen.

Simple, functional, and exactly what I always needed myself.

If you like the design, I would be happy about a Boost from you 🚀
