Marker holder (for colouring feedstock)

thingiverse

Experiment with colored markers in the feedstock inlet led to colorful prints. The Marker Organ was born as a way to attach multiple colored markers and choose which one or combination to use for printing plastic. This first attempt features a simple clamp over the feedstock holding a single marker. To use, measure your marker's dimensions, modify the .scad file by changing "bolt_dia" to your bolt diameter and "pen_holder_bottom_id" to your marker's diameter. Measure the length of the part you want to grip (including the marker tip) and make it shorter for better grip and feedstock contact. OpenSCAD will render the design, export as STL, and print the file. Assemble by clamping two parts together with bolts around the feedstock and insert your chosen marker through a side hole. Enjoy colored prints!
