Parametric Profile 5 – 40x20 Extrusions

This model provides a fully customisable version of the classic 40x20 aluminium extrusion (Profile 5), designed for makers who need flexible, parametric frame components for their projects. Based on the standard 40×20 profile with 5 mm slots, it replicates the widely used modular system featuring four open grooves compatible with M5 hardware and common accessories.

  • Fully parametric length customization
  • Standard 40×20 profile geometry (slot 5 compatible)
  • Designed for easy integration with T-nuts, brackets, and connectors
  • Lightweight and printable alternative for rapid prototyping
  • Center hole optimized for M3 heat-set inserts

Perfect for:

  • DIY frames and structural prototypes
  • 3D printer mods and accessories
  • Electronics enclosures and test rigs
  • Educational and design experimentation

Scale, adapt and print to fit your project!
