Print screws sideways for max strength—tensile load runs along print layers
No supports, no retraction needed—makes fast, hassle-free printing easy
Includes smooth profiles like sinusoidal and quadratic for jerk-free moves
Open-source OpenSCAD library—customize thread pitch, size, and more
Perfect for DIY workshop jigs, mechanical prototypes, and custom fixtures

This is an OpenSCAD library of 3D-printable screws engineered specifically for the quirks of FDM printing. Instead of standing upright (where layer lines are weak), these screws are designed to print sideways—so tensile loads run parallel to the layers. The result? Way stronger threads that won't snap under load.

The library supports multiple thread profiles, including osculating quadratic and sinusoidal shapes that let your printhead glide smoothly without harsh direction changes. You can print faster, skip supports entirely, and even disable retraction. It's ideal for workshop tools, custom jigs, replacement parts, or any project where you need functional screw threads without the hassle of tapping or inserts.

You'll get the digital OpenSCAD files to generate screws in whatever size and pitch you need. Just load the library into OpenSCAD, tweak the parameters, and export your STLs. The repo includes examples and documentation to get you started, plus the option to chop off portions of the screw for even cleaner sideways printing.
