A friend asked me to make a bookmark with a pencil clip on it. So I did. The regular bookmark will hold standard pencils and regular ball point pens (straight barrel). The big clip will hold the bigger pens that you might get as swag at conventions or whatever (usually the clicky pens). At any rate, I included the Inventor file if you feel like the design needs tweaking.

When printing, orient this with the long thin edge on the bed and use a brim for bed adhesion. Otherwise this won't stick to the bed and it'll end up curling on you. At least that was my problem and fix.
