4 pieces of MakerBeamXL 3D printed end caps. You can screw these end caps under the MakerBeamXL beams (15x15mm). These end caps can also be used to protect the sides.
The 3D printed end caps are NOT compatible with OpenBeam unless you create tapped ends yourself. You can use our thread forming screws to do this (art. no. 101653).
We have drawings available (.STP, .DXF, .PDF).
