Lost a cap for your Crayola Supertips marker? This 3D-printable replacement cap is designed to fit snugly and keep your markers from drying out. To ensure a perfect fit, I created four different sizes (11.5mm, 12mm, 12.5mm, and 13mm) since different filament brands can have slight variations. PLA matte worked best with 12.5mm, while regular PLA fit better with 13mm. I recommend printing all four to find the best fit for your filament. Print it in your favorite color and extend the life of your markers! Ideal for parents, teachers, and artists who want to keep their supplies in top shape.
