BOSL2 is a large OpenSCAD library providing shapes, masks, attachments, rounding/filleting tools, math utilities, and shorthands to simplify parametric 3D modeling. It requires OpenSCAD 2021.01 or later and is explicitly labeled beta code.

Use cases

  • build parametric 3D models in OpenSCAD more easily
  • position model parts relative to each other with attachments
  • round edges and fillet corners of 3D shapes
  • sweep profiles along paths to create complex objects
  • subtract mask shapes from object edges
  • write shorter, more readable OpenSCAD code with shorthands

When to choose

  • you model in OpenSCAD and want easier positioning and composition of parts
  • you need rounding, filleting, or edge masks that are hard in native OpenSCAD
  • you want a comprehensive toolkit of shapes, transforms, and math helpers for CAD scripting

When to avoid

  • you use BOSLv1 code, which is incompatible with BOSL2
  • you need a stable, non-beta library and cannot tolerate reorganization
  • you don't use OpenSCAD or work outside parametric CAD scripting
