Flexible Coupling param. with 2 different inner holes and speretae spring parameter

thingiverse

This code is based on Thingiverse's item number 44078, which I have customized to allow for two distinct hole sizes (D2 and D2B). This version offers greater flexibility in altering spring parameters by adjusting the spring inner radius. The couple can then be adapted to fit various-sized axes more easily. The provided images demonstrate a print test using 45% infill and PLA, showcasing good top print quality despite larger overhangs. Key variables include outer diameter (D1), inner diameters 1 (D2) and 2 (D2B), inner diameter 3 spring (D2S), total height (H1), base height (H2), number of flexible elements (N), screw hole diameter (D3), nut hole diameter (Dnut), nut hole thickness (Hnut), flat shaft thickness (B), screw hole distance (H3), and springs resolution (SLICES).
