New product design

Hello, my name is Mohi, hope all is well with you. I've attached a super basic (slightly embarrassng) napkin sketch for this new product I'm trying to develop. I'm basically just trying to turn my sketch into a new sketch that's good enough to turn into a 3D model, or ideally if it's possible, to turn my crappy sketch into a 3D model directly. The sketch of the product is really just the outer case, there's no functionality to it at all, I'm just trying to get a model prototype of the products look and feel, the inner workings will come later. Essentially its a pretty plastic box.. I'm hoping to get my idea out of my head and into a 3D model that I can send off to a 3D printer for prototyping. The completed prototype will look and function much the same as a traditional laser printer. I'm trying to design the outer case of a printer if that makes sense, but the final prototype will be used in the kitchen so it would need to be more aesthetically pleasing toward a kitchen rather than an office environment. I've attached an image of a sketch, with labels 1 through to 4. There would need to be a few separate pieces of the design too, that connect together during assembly. It has a base, a top cover, and a small lid within the cover too. Hope to make more sense by the end of this. 1/ represents a flip top lid on top of the printer, as far to the back as possible, ideally around 150mm wide. 2/ represents 4 small square or circular cutouts for the printers control buttons. 3/ represents a cutout almost the entire way across the front of the printer, stopping 10mm from the edge on either side - this cutout would need to be around 20mm wide. 4/ represents a cutout almost the entire way across the front of the printer, stopping 10mm from the edge on either side - this cutout would only need to be around 08mm - 10mm wide. Ideally the printer would measure say 300mm wide x 250mm long and 80mm height. That's it in a nutshell really. I've also attached image of a black printer that I'm drawing inspiration from for the look and feel of the design. This is basic explanation of what I'm trying to accomplish however im very much open to your own twist on the design, whatever you feel. So that's it, a 3d printable file... I'm hoping to find someone who can get the design out of my head because I'm obviously useless at drawing and I'm struggling to explain my vision. Hope this makes sense. Thanks for your time. Mohi
