May not be what your after Colin, but I have brand new and never used 3D parts and two of the community controllers.
These were printed by an experienced professional and owner of an SFX build. I also believe he makes them even better than the recommended specs.
I need to put them on the MM soon but let me know if interested, they could be sent in a jiffy as I'm only over the water in Northern Ireland. Not sure what I paid but will look and would even take a small loss on these.
