This template generates mounting brackets with a reinforcement bar. The length, height, width, thickness, and screw diameter are adjustable. It is also possible to apply chamfers on the openings to accommodate the screw heads.

Two openings in the reinforcement bar allow the screwdriver to pass through. Support generation is not required for printing these brackets.

The L-bracket must be printed flat on the build plate:

3D-printable bracket models

3D-printable brackets make it possible to reinforce or assemble two perpendicular surfaces with precision. Used for shelving, framing, or light mechanical structures, they offer a simple and adaptable fastening solution. Their parametric design allows easy adjustment of height, width, thickness, and hole diameter to fit any assembly configuration.

For compact applications or precise assemblies, a small symmetrical bracket provides a balanced and rigid geometry, ideal for light supports or discreet fixings. When higher strength is required, a large mounting bracket ensures excellent mechanical resistance and long-term reliability.

For assemblies requiring simple holes and full contact, a large bracket without chamfered holes is ideal for round-head screws, providing complete surface contact and optimal compatibility with different types of hardware.

These 3D-printed brackets stand out for their ease of printing (flat, without supports) and well-distributed rigidity. They form a reliable base for any setup requiring a strong right angle, whether for domestic, technical, or experimental use.
