These are the thighs of the DOOM Slayer from the DOOM game 2016. I made these 3D files on my own for my DOOM Slayer cosplay. You can see the whole build process for my cosplay including these pieces on this forum: https://www.405th.com/forums/threads/yet-another-doom-slayer-praetor-suit-2016-build.52519/
All parts are smooth and easy to paint as I kept the details to a minimum.
Only the 3D files for the parts shown in the pictures are included. It is only the thigh and the back part of it. All files are for the right side, so simply flip them for the left side.
I printed all files on a my Creality CR-10 which is 300x300x400mm with support and raft. Check the size before printing, as they are uploaded in original scale (which is quite big), I am 195 cm (6.4 ft) and the doom slayer is about 203 cm (6.8 ft), so keep that in mind if you are not that tall. You still would need some underlying structure to glue these pieces on after printing like EVA foam.
Check out my profile for more cosplay pieces of the DOOM Slayer. I offer some other body parts as well.
