Update: Added 2 slot and 4 slot OPTIONAL extenders so you can make these as tall as you dare. :)I decided to remix the Pen holder for 13.4mm and 8 Sharpie Pens (instead of 16). This should also fit the thin expo white board markers. Printed fine on my MP Prusa i3.Suggested Print process:Print the “DNA_Helix_Sharpie_Pen_Holder_13mm_BothParts02
