MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
Did you try printing it bigger? I ask because I have the standard S7 earbuds too and I printed this without reading the comments first (dumb I know but now I have a gift for someone). Of course they don't fit because of the long plastic on the ears and the inline mic.
If you printed it bigger and it works for you, what scaling did you end up using?
