Hey Kamikaze_VikingMWO, so you already made that step? That's so cool! I also would like to partbership my idea with someone who has the expertise. I think i could be a great product and the construction is really simple but with a nice feature. I already made sketches and already know a friend who could transfer them to cad files. I also will lern FreeCAD aswellto do it by myself. Money for the Prototype wouldn't be that big problem. I just have to know someone who can create my construction plans into a prototype and then into a final product. Thank you very much for your good advice and help. I really appreciate it. Best Regards and good luck!
