X/Y Dimensions Double in Size When Exporting to STL

[jsgrill]

I made a very simple hexagon design because I wanted to test something out. However, the X/Y dimensions are doubled when I export the design to a STL and open up in either of my two slicers (Prusa and Cura). 

• I created the object using mm (X= 31.25 mm, Y = 36.66 mm, Z = 6 mm). 
• I tried all three methods to export/save the object as an STL.
• I open the file in Prusa or Cura and the object dimensions are now x= 63.5 mm, Y = 73.32 mm, Z = 6 mm.
• I even started over from scratch to recreate the object and still got the same result.

I am confused on this one as it has not happened before.

Yes, I know I can resize the object to the correct dimensions in the slicer but this is still an annoyance that I don't want to have to deal with in future files.

Thank you for any help.

Please attach BOTH your Fusion 360 model and the exported STL file.  If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

Added the files. Thanks.

I am a little puzzled, the model you supplied is not to the size you say you modeled it to.  I superimposed the STL you supplied over the Fusion 360 model and it matches size perfectly.  I then modified your sketch to the dimensions you said the original should be and then exported it as a STL and superimposed it again and it is a perfect size match. 

Looking at your original sketch, you used dimensions from the center to your hex edges.  Could it be possible you are meant to use a dimension across the full width?  Video will trace it all.

Looks like I misunderstood creating the hex and thought I was doing diameter instead of radius. So, user error. Thank you for entertaining my nonsense.
