Great, now if I can just figure out how to get my system to stop trying to use the broken one from pleasant3d (also included with Cura) and use this instead…
yeah that was my problem too. I just removed cura and autodesk360 since I didn’t used it anyway. 
Cura is my primary slicer these days, so removing it isn’t really an option…
I did try removing Cura (temporarily hiding it in a zip file), didn’t help.
HA! If you can’t beat 'em, join 'em. Adding com.pleasantsoftware.uti.stl to the LSItemContentTypes array in the quicklook plugin’s info.plist made it work!
@Whosa_whatsis cool, great work!
