I saw some props by a TF2 prop site (https://www.propfortress.com/) and really liked how "reload-able" the props were! So after a few minutes of watching a YouTube tutorial and figuring out how to un-group loose parts in Blender, I bring to you... a fully reload-able TF2 winger (moving parts not part of a complete firearm)

If you want to do this yourself, check out Newportt1's tutorial (https://www.youtube.com/watch?v=nq65Lhf0REk&pp=ygUTaG93IHRvIDNkIHByaW50IHRmMg%3D%3D)

Happy printing!
