I have a flat 2D image that I need transformed into a 3D-print-ready model. Beyond simply giving it thickness, I want the piece to gain character through extra geometry: "Final stl file should look like.jpg" is the model I am looking for at the end. The interior should be hollow, because i have to run through the object a "red fiber optic LED with 5mm height and 5mm width" Between the small "red" gaps would be nice if the "red fiber LED" would pass through in a 5mm/5mm tunnel in such a way that when I look at it it's not visible so to speak, also the back should be somehow detachable, if I have to change the "fibre". The whole object should be 180mm large and 10mm thick.
