Hello, I am trying to modify my CTC dual extruder 3D printer. I would like to add a spring loaded extruder along with a compatible nozzle and metal thermal barrier. When I look on amazon I find various part sizes; i.e., diameter sizes, thread variations, MK8, MK10, and so forth. As a result I am confused on what parts to purchase because I am uncertain on what parts are compatible with one another, not to mention compatibility with my CTC 3D printer. So, before I spend the big bucks, I just want to make sure everything is compatible as I have already ordered parts that are incompatible. So my question is, can anyone send me some links (preferably amazon) to some compatible parts so that I can feel confident when purchasing the the following parts: spring loaded extruder, nozzle, and thermal barrier. FYI- In case you are wondering, i am trying to get away from using PTFE tubing so I can hopefully avoid clogs and use exotic filament.
