Pen housing inspired by Prusa's dual Z axis servo motors screw actuator shafts.
Amazingly it provides a more secure and comfortable grip.
Printed in PET-G and uses a BIC pen ink pen element, from a BIC Round Stic or Ultra Round Stic pen.
Prints in an vertical upright position.
As a bonus, blow across the hole before you install the pen element and it can make a nice whistle tone too!
i named it Rotini as this pen also resembles the pasta noodle. So use you noodle and write a story, book or even just a simple letter.
The author marked this model as their own original creation.
