Do you struggle to find the pen you knew you had in the mess of your backpack when you need it fast to note something down? 

Even if you're sitting at school, out walking, shopping or sitting in a tent you will always have a pen available.  With this pen clip you can have up to three pens at an arms reach. It simply clips to the shoulder strap of your backpack. 

The back part of the clip should allow thick shoulder straps as well. Holds medium to large pens as the inner diameter of the holder is 10 mm (Regular Bic pens as an example is around 8 mm in diameter).

Update:

• Added Pen Holder For Backpack Strap 8.5mm that should fit smaller pens. I have not test printed this version.

Printing instructions:

Print with one of the sides down like shown at one of the pictures.

The model in the picture is printed on a Bambu P1S with:

• Filament: Bambu PLA Basic
• Infill: 15%, Gyroid
• Supports: No
• Adhesion: No
