Nov 5, 2023 · Edit Dec 7, 2022 Updated the algorithm used to interpolate between samples when creating a helix with a filled in core. This fixed some artifacts that could happen in some cases and improves accuracy in all cases, although it made the code run somewhat slower. Optimized one of the internal functions by doing some paper pre-calculations. Removing the "work-in-progress" designation Yet another ...

OpenSCAD provides two commands to create 3D solids from a 2D shape: linear_extrude() and rotate_extrude(). Linear extrusion is similar to pushing Playdoh through a press with a die of a …

Crossed Helical Gears in OpenSCAD. This project shows how to generate gears in OpenSCAD that can be used to transmit torque between two non-parallel, non-intersecting shafts.

Mar 14, 2016 · It can not be used to produce a helix or screw threads. (These things can be done with linear_extrude() using the twist parameter.) The 2D shape must lie completely on either the right (recommended) or the left side of the Y-axis. More precisely speaking, every vertex of the shape must have either x >= 0 or x <= 0. If the shape spans the X axis ...

Nov 5, 2023 · Yet another OpenSCAD library to create helices. There is plenty of libraries out there, but most of them are unpredictable. The height, width, angle, etc are not respected, making it very hard to create precise model. This library is very precise, flexible and easy to use.
