Introduction: 3D Printed Pen Holder

About: My name is Sabine. I'm a hobbyist with a variety of interests, including 3D printing, tinkering, music, stories etc.

Some people need support by holding a thin pen/pencil, they need a larger grip/surface. Here is my DIY idea: A 3D printed pen holder.


  • 3D Printer
  • flexible Filament
  • Pen
  • Tinkercad

Step 1: Tinkercad

I designed up to three models in Tinkercad to figure out which shape worked the best. I went for the triangle one. To me, this was the most comfortable shape to hold in hand.

The size of the lead-hole for the pen depends on the thickness/diameter of your pen and the expansion of your filament. The length is around 2 inches or 50 mm.

Step 2: 3D Printing

The pen holder was 3D printed on the Ender 2 (before the nozzle clogged!) with flexible black filament. To be honest, the holders fit is a little to tight but I could not print another one because my 3D printer had extruding issues. The replacement nozzle is already ordered but will not be delivered in time.

Slicer settings (ideamaker):

  • Shells: 3
  • Infill: 15 %
  • Platform addition: Brim only
  • Layer Height: 0.2000
  • Support: none

The softer your flexible filament is the more comfortable it will be. I've used another flexible filament for a prototype which doesn't felt so good.

Step 3: The Pen and Its Holder

With more effort as intended I plugged the pen into the holder. But at least it looks pretty cool on the white pen. So, writing down and sketching out my next instructables projects will be a relief with this kind of support.

The positive side effect and additional benefit: The holder stops the pen from rolling over the table and dropping to the ground.

Thank you for reading, watching and paying attention. Please let me know if you've made one as well. Hopefully Auf Wiedersehen in one of my next Instructables.
