Professional connector system engineered in Siemens NX for 25x25mm square steel profiles (1.2mm wall thickness). This is not just a 3D model, but a complete engineering solution for structural DIY projects, modular furniture, or industrial prototyping.
The 8-File Master Pack
This bundle includes two distinct versions of each joint type to cover every manufacturing need:
4x Solid-Body Joints: Optimized for 3D Printing (FDM/SLS). The solid core allows you to control structural strength via slicer infill settings.
4x Hollowed-Core Joints: Specifically engineered for Injection Molding. Designed with constant wall thicknesses and internal ribbing to prevent sink marks and optimize cooling cycles.
Engineering & DFM Features
DFM Optimized: All files include precise draft angles (sformi) for easy mold release.
Precision Fit: Tailored for standard 1.2mm tube thickness, ensuring a secure, wobble-free connection.
Mechanical Integrity: Stress-concentrating corners have been replaced with engineered fillets to increase overall structural load capacity.
Technical Specifications
Tubing: 25mm x 25mm Square (Steel/Aluminum).
Wall Thickness: 1 mm.
Software: Siemens NX.
Recommended Materials: PETG-CF, ASA, or Nylon for 3D printing; PA6/PA66 for injection molding.
What’s in the Box?
8x High-Precision STL Files (4 Solid + 4 Hollowed).
NURBS STEP Files Included: Essential for professional CAD modification and CNC/Mold making.
