I made this modification to make the model design smooth, without holes for the Moza R5 control standard. The center screw holes were also modified, in the Moza model they were 60mm, this modification aims to use the model with the 70mm standard.

This model was designed for M5 screws. I haven't been able to print it to test its strength yet. If you do print it, please comment on your print settings and share your feedback. Feel free to modify and improve the model if you want...
