I made this model specially for carbon steel material, and as you can see in the analysis static picture this model can bear up to 200Kg and just bend a little, that is exactly what i expected.
Indeed this model is designed for those who work all the time with a laptop and want to control the whole device in a comfort space (freelancer, gamer, ....)
and I should tell you that if you buy this model I will give you a flat pattern to make this design with sheet metal for free.
