Buddy of mine wants a simple 3d model creating of this shape ready for printing. I’ve never modelled anything for 3d printing before and would like some advice please. I can create the basic shape well enough but the letters are a point of unknown for me. Ultimately this is gonna be for some kind of necklace so would modelling the letters separately and simply placing them on top work well enough? Or would engraving the letters INTO the model work better?
