Pen Holder

thingiverse

Pen holder designed to accommodate 1, 7, 19, 37 or 61 pens is available. An OpenSCAD file (.scad) for custom modifications is attached. You can alter the cylinder radius, wall thickness, base height, and more. The shape of a single component can be straight or created using a Bezier curve. This design was inspired by "48 Art Pencil Holder" from Gizmoticist: https://www.thingiverse.com/thing:316755 Recommendations for printing include no support, no raft, layer height: 0.2, line width: 0.4, wall thickness: 0.8. In my models: faces= // derived from [6,12,18,24,...] ; single cylinder resolution count_z= // [0,1,2,3,4] ; zone number (from center to external cylinder) radius=8; // single cylinder external radius thickness=0.8; // wall & bottom thickness count=3 count_z (count_z+1); // [0,6,18,36,60] ; count+1 = number of cylinders distance=cos(180/faces) * (2radius-thickness); // between centers of cylinders Thickness_of_wall = cos(180/faces) * thickness Inside_hole_dimension = 2 cos(180/faces) (radius-thickness) Inside_hole_dimension (for radius=8 and thickness=0.8): 12.47 for faces=6 13.91 for faces=12 14.18 for faces=18 14.28 for faces=24 14.32 for faces=30 14.37 for faces=48 ... Inside_hole_dimension should be greater than pen diameter.
