mechlib

Source ↗

Parametric mechanical components for Python. Every part below is a function that returns a watertight, FDM-printable mesh in millimetres. Spin it, retune it live, copy the import.

Install pip3 install git+https://github.com/m-esm/mechlib

Use

import mechlib as ml

body = ml.rbox((40, 24, 12), r=3)                                  # rounded block
body = ml.sub(body, ml.teardrop(4.1, 50, axis="x", up=(0, 0, 1)))  # print-safe bore
ml.export_stl(body, "bracket.stl")                                 # watertight gate

Utility API

Non-visual CSG, probing, fitting, and selection helpers. These have no geometry to show; call them on meshes you already have.
