Adafruit is celebrating Lunar New Year🐍 Wednesday 1/29/2025. In combination with MLK Day, shipping could be delayed. Please allow extra time for your order to ship!
This is a remix of the Hypercube pen holder to fit onto the CR-10 (although not as fancy as his updated version). This pen holder can be used for pens with a diameter between 8 and 11 mm.
NOTE: this pen holder can only be used if the fan mount has been removed (and for example replaced by an OEM Fang), so the two remaining holes can be used.
Furthermore, you will need:
Two 10 mm M3 screws
One >16mm M3 screw
Two M3 hex nuts
Three M3 washers (optional)
The images show how these should be assembled.
I’ve also updated the knob for a better grip. To use this pen holder, unplug the connector of the extruder stepper motor and set the bed and nozzle temperatures to 0°C.
Edit
I’ve uploaded a second version which has some vertical movement. It is not optimal, as there might be some unwanted rotations or movements along other axes. Can be printed in the same orientation as attached on the printer. You can use the same knob.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat and our Discord!
