The sword, shield, crossbow, helmet, and some of the armor pieces connect together with press fit pegs. The pegs however are sized perfectly to the hole, so if your printer has any sort of shrinkage they will not fit in them. I had to modify every single peg with negative part modifers to make them actually fit together.
The armor itself also does not connect together, One of the photos shows a pauldron with the pegs on it and it is the only armor piece that actually has the pegs. All of the chest piece and remaining pauldrons do not actually connect together and required me to use a soldering iron to melt them into each other.
I reached out to the author for clarifaction to see if i was making mistakes somewhere and never heard back from them after 2 weeks.
This should not be marketed as cosplay armor simply due to the fact that you can not actually assemble the pieces to wear them without heavily modifying the files yourself.
