Guides
Short, practical guides to designing real, working parts for a laser cutter or CNC — the geometry that matters, the laser-specific gotchas, and how to export standards-correct SVG/DXF with the free GearForge generator.
How to design laser-cut involute gears
Module, tooth count and pressure angle; undercut and trochoidal root fillets; kerf compensation; and the materials that make good gears.
Timing-belt pulley generator: GT2, HTD, T5
Which belt profile you have, the OD = z·p/π − 2·PLD formula, and laser vs 3D-printed pulleys.
Involute spline generator (ISO 4156)
Why splines beat keyways, the parameters that matter, and generating mating shaft + hub cross-sections.
