Safety Stand

If you don’t have aluminum extrusions by hand, you can purchase the safety stand section as listed in the Bill of Materials.

We present one solution as shown in the image below. We use 300mm 4040 aluminum extrusions (*3), 700mm 4040 aluminum extrusion (*1), and 100mm 2020 aluminum extrusion (*1). For the 4040s, 7ou can use 500mm 4040 aluminum extrusions (*4) as in the bill of materials without any problem.

Pay attention to how we arrange the extrusions and place the connectors to maximize the stability of the stand. We use 5 sets of 4040 corner connectors in total. For the 3D-printed connector between 2020 and 4040, you can find the sliced plate in the MakerWorld and the CAD file in the Onshape document. We also put optional 3D-printed feet in the same document in case you want to avoid scratching the floor or the table.

Note

This is not the only possible solution, but it is essential to ensure strong support along the axis where a significant torque will be applied when mounting the robot onto the stand.
