Here is the most complex project I have ever worked on.
Human Anatomy kit has all muscles and bones labeled. Also includes muscles groups and colour-code. Above all for those, who are interested in small details you can also find muscles striation as well.
Gumroad will be available soon.
This has been a massive help for me to understand anatomy better, hopefully it will for you as well.
