After I finally received all parts I needed for my low budget Chimera upgrade, I spent the last 3 days on developing and building the parts for the upgrade. I mostly just remixed original parts or other great Anet Upgrades from Thingiverse. As a stress test I printed the dual color frog from nervoussystem (https://www.thingiverse.com/thing:329436) and the result seems very impressing to me considering that I did not spent more than absolutly necessary. If you have any questions, feel free to ask and happy printing!
Some parts like the x-carriage require support structures. I printed all parts with 0.2mm layers and an infill of 20% with a triangle pattern.
