It took me one month of work. And this is 99% of my exclusive work. Only aluminium plate has been finally CNC laser cut by the specialized company according to my project because my own performance with 200 drill holes and cutting with Proxxon professional spindle fretsaw was ineffective method to do this. It was precise but too time consuming and costly for me. I know I can do it on my own too but at to high cost of my own workload. Sorry that without comments of how to do. But this is my own idea and I only want to promote myself this way.
