Actually, I do think I have a question. I'm a larger dude, and when I re-scaled the pieces to print, the split up pieces don't fit on my printing bed. Are there any pointers you have so that I can split it up in order to print it without failing? Things like overhang and grip on the heatbed are my main concerns. Though they can be fixed with supports and brims respectively, I want to try and avoid those.
Spliting up the models into 4ths or 8ths doesn't work well with the chest for the above reasons
Are you familiar with Blender at all? If not, you will be.
Blender is a free 3D program you can
download from their site. You can use the thumbnails I've attached or you can watch the video I linked down below.
Once Blender is installed, import the .stl armor file that needs to be cut:
Next, Insert a Mesh Plane into the project and be sure to click on the little plus size in the top right corner:
Change the x and y dimensions to 400 each:
Look on the lower right side and bring it out until you see that little wrench. Left click it:
Go to the upper right side and left click on the piece of armor that needs to be cut. Make sure it is highlighted in the center:
Go to the bottom right and click on "Add Modifier" and select Boolean.
Change the options you have in the picture below. Notice, once you select everything, the armor is gone below the plane:
Export the file to a .stl:
For the other half, just change that one value under "operation" to say "Intersect"
Now export the lower half and you have successfully cut a piece of armor in half.
This video does the same thing...only the Blender he is using is a little older:
