Here's the next thing I'm working on, a technique to print logos and inscriptions in 2 colors on my 3D printed fly reels using the E3D Cyclops 2 color switching hot end and BondTech QR extruders. I've dreamed about being able to do this for several years and figured out the design and slicing to pull it off but I've not had the ability to actually print it until now. This is a first attempt and is about 95% of the way there. Just a few refinements and it should be ready to go. This one is done in translucent smoke PLA in clear PLA. The logo is three .2mm thick layers. The next version will have a single clear layer on the surface completely encapsulating the logo.
