Sunshine Rainbow Little Zebra Click Pen

[First Grader - Shi Yize] I'm a first-grade student who just started elementary school When I started learning to write, my mom bought me a holed pen I always felt my hand would start sweating after writing for a long time And when drawing with colored ballpoint pens, I was always curious about how much ink was left in the refill So when designing this little zebra pen, I incorporated zebra stripe elements which perfectly solved the small problems I was curious about I drew and designed it myself my dad helped me refine the design draft and model it constantly optimizing the model and testing it many times the hollow parts always had various issues My dad and I discussed improvements for several days before finally getting a relatively perfect model

[Dad] This zebra hollow pen is something my child and I repeatedly tested, adjusted, and refined together We finally settled on the most suitable size for children to grip—a pen body diameter of 9.9mm, and the entire pen weighs only 9.5g, making it comfortable to hold for a long time At the same time, we challenged the printing limits of a 0.4mm nozzle which placed high demands on printer accuracy, interlayer adhesion of materials, and bed adhesion Only then did we finally create this exquisite and easy-to-grip hollow pen
