An OpenSCAD screw library for screws that are especially **optimized for the limitations of the FDM printing process.** Get the library on github: https://github.com/mechadense/scad-lib-FDMscrews (alternative name: **"flatscrew library"**) Highly suggested is printing the screws sideways with parts of the screws chopped off (library supported). **Tensile loads on the screws is now parallel to the printing layers.** This: ★ gives much stronger screws ★ allows printing without support ★ allows printing without retraction ★ (allows for fast printing with the default profiles) Among the supported profiles are soft ones for fast printhead-jerk-less printability. ★ default is osculating quadratic ★ also very good is sinusoidal ★ there are a few more profiles available **Known problems:** Unfortunately the currently implemented triangulation method does not allow for proper sawtooth, rectangular and steep trapezoidal profiles. The triangulation scheme needs to be switched out for such steeper profiles.
