Update: this project was discontinued due to my lack of interest after buyng a prusa instead of building a DIY UM2. as a result, I have decided to release the .f3d file so all the people who have shown an interest in this can download and edit it. Just keep in mind that I designed this with less than 4 months of experience under my belt at the time.
I downloaded and 3D printed a UM2 mount for the E3D Titan( https://www.thingiverse.com/thing:2749539) , but didn't have any compatible fan mount that I liked, so I made my own that attaches to the v6 fan and the 2 holes on the titan/v6 mount dedicated to a sensor adapter.
This design is W.I.P, and thus far hasn't been tested yet, so print this at your own risk until I've improved upon the design, unless you feel like testing it. It should be functional though, unless i missed something.
The current design prints in 1 piece with holes for plugs for securing the radial fans, but lacks any mounting option for sensors.
