These are for cosplay Jango Fett's since it is very hard to get measurements for these and no one has created any STLs for these. These are based off of Dark Side's (from TheDentedHelmet.com) original aluminum knee darts and gauntlet darts. Please do not sell these because they are meant to be...
Credit to Dark Side for originally making these greeblies since all the measurements were from people who already have his greeblies.
I don't think these are 100% exact to his aluminum goods, but they are pretty close.
Also a shoutout to droidbait and Madrox from theBHG.net for the measurements to make this possible. Hopefully some fellow Jango's can benefit!
