Summary

code based on version of thingiverse.com/thing:44078
I modified the original code, so that two different hole sizes (D2,D2B) can be specified (inner diameters). This version allows for a differenr spring inner radius to change the spring parameters more easy - The couple can then be used to couple to different sized axis.

Instructions

Example:The images show the print test using a infill of 45% and PLA. The top still prints well with this larger overhang.

// OUTER DIAMETER
D1 = 25;

// INNER DIAMETER 1
D2 = 2;

// INNER DIAMETER 2
D2B = 8;

// INNER DIAMETER 3 SPRING
D2S = 20;

// TOTAL HEIGHT
H1 = 50;

// BASE HEIGHT
H2 = 10;

// NUMBER OF FLEXIBLE ELEMENTS
N = 12;

// SCREW HOLE DIAMETER
D3 = 3.5;

// NUT HOLE DIAMETER
Dnut=6.5;

// NUT HOLE THICKNESS
Hnut=2.5;

// FLAT SHAFT THICKNESS
B=8.5;

// SCREW HOLE DISTANCE
H3=4;

// SPRINGS RESOLUTION
SLICES=16; //[6:36]
