Customizable Double Helix Pen Holder Cup

thingiverse

This is a pen holder cup featuring sides comprised of double helixes. It prints best when using supports, but breakaway supports are not really an option. Instead, wash away supports would be required. The design is customizable, allowing you to change the height and diameter, with the number of double helixes automatically calculated. You can either print the entire thing in one STL file or get separate STLs for the top rim and half of the helixes, and the bottom plate and the other half of the helixes if your printer has a dual extruder with multiple colors. The bottom plate is 4mm high, so when using multiple colors, place both STLs on the build plate and then move the colorB STL up in the z-axis by 4mm. Added STL file for a 110mm (height) x 35mm (radius) holder. Updated design with optional supporting spirals for improved printing.
