Carolina Panthers Keychain

thingiverse

I recently obtained a keychain representing the Carolina Panthers for their 2015-2016 season and proudly wear it while I'm reminded to "Keep Pounding!" However, when I export STL files from Inventor to later fabricate them on my own Ulitmaker 2 3D printer or send out for commercial production with a Stratasys machine, my model's dimensions inevitably go astray. Yet, surprisingly, there is often a conversion factor present that allows me to adjust and scale it back to where it should be, nearly always requiring a reduction of approximately 60 percent when printing on Stratasys but needing to enlarge by an impressive 10 times in order to print effectively with my Ulitmaker 2.
