3D Print Calculator and invoise program

About

I recently built a tool called 3D Print Calculator that helps calculate the real cost of 3D prints (material, electricity, maintenance, waste, etc.). It can also generate quotes and invoices and send them directly to customers. I originally made it for myself when I started selling prints, but I thought it might be useful for others too. If you're interested, you can try it. If you'd like, I can also activate 14 days of free Pro for you to test everything. I'd really appreciate any feedback! 😊
