Elektriktrick STL and GCode Quicklook for OS X


QuickLook is a wonderful thing on Mac: just hit the space bar with any file selected, and a big preview of that file will be shown instantly. Unfortunately this will not work for STL files. Older QuickLook implementations will no longer work for Mavericks as OpenGL rendering is no longer possible due to sandboxing. Elektriktrick STL and GCode QL uses standard graphics to get around that limitation, It works for QuickLook previews as well as for Icon previews.


  • Download Elektriktrick STL, dxf, and GCode QuickLook V1.1.0 for OS X 10.7 and above


Download and open the disk image. Drag the Elektriktrick application into the Applications folder. This will alos install the QuickLook plugin.

Note that the Elektriktrick app does absolutely nothing at this point. It's merely a container for the plugin.

  • Download Elektriktrick STL, dxf, and GCode QuickLook V1.0.3 for OS X 10.6 and above
  • Download Elektriktrick STL and GCode QuickLook V1.0.2 for OS X 10.6 and above
  • Download Elektriktrick STL QuickLook V1.0.1 for OS X 10.6 and above

Instructions for 1.0.2 and older

Unzip the .zip file and move the resulting ElektriktrickQuickLook.qlgenerator into /Library/QuickLook if you want this module for all users, or into ~/Library/QuickLook if this is only for you.

If the zip file contains a disk image, open it and simply drag the left file onto the right folder. You need to enter your password to do this.


If QuickLook does not work right away, go to the shell and run qlmanage -r and qlmanage -r cache or log out and log back in again.

If it still does not work, and you see a white cup on a dark brown surface as a preview, a software named Pleasant3D' is installed somewhere on your computer (Autodesk360 and Slic3r install it, for example). If you want Elektriktrick to work, you need to delete Pleasant3D completely (even empty the trash). I will try to fix that in the next version.

If that still does not solve the issue, please open the Terminal in /Applications/Utilities/Terminal and enter this command qlmanage -d 2 -p oneOfMyFiles.stl > ~/Desktop/qldebug.txt . This should generate a file named qldebug.txt on your desktop. Please send that file to elektriktrick@matthiasm.com.
