I need a logo for a 3d printing company. The company's name is Overlay - 3D Engineering. I'd like it to have a professional look (or at least that it doesnt resemble a "hobby" approach to 3D printing). I am 29 years old, so the logo should provide a young, yet mature feeling to the customer. The company also has many products related to offroad/adventure/rally motorcycling (a bit like the Dakar desert race). Although this is the primary market, I also sell products to other markets, so I dont want it to be too "specific" to this theme. I would like something simple, favourite colours are yellow, green, purple and purple-ish pink, dont really have to be all in the design. OVERLAY should be the main word, 3D Engineering should be smaller but present as well. The logo (symbol, per say) should be related to engineering and 3d printing.
