Instructions for adding the badge can be found here:

Tesla uses a jig to align the badge:
- 2091866-00-A REAR DM BADGE JIG
I found a third-party who appears to sell this jig:
JTC TOOLS 4 TESLA
jtctools4tesla.com
I also looked in the "service tools" section of the parts catalog, and it looks like Tesla has a different jig as well:
epc.tesla.com
And that's available through a third-party:
www.mpcmfg.com
Hopefully one of those will work for you. Or just eyeball it.
