This thing was created using the Thingiverse Customizer app. You can also check out the original thing at: http://www.thingiverse.com/thing:70494. To build this thing, you'll need to use the following options: Wing count set to 3 The wings will be 16mm thick Each nut's shoulder is positioned 2.8mm from the side and 2mm above Hollow out the top surface by about 7mm If specified, attach a single hex nut on top that goes up to 1 thread deep. The thin wall of each wing has a diameter of 10mm. A total external width is specified as 60 mm To ensure consistent shapes use an approximate roundness ratio of around 50 percent You can see it now - each one has 14.6 mm wide nuts Last step is to cut threads on top so that you may screw in whatever you like at about a depth of 8mm.
