Default Setting up a case using .stl files

Hello, I have been trying to set up a simple case in OpenFOAM of fluid flow through a pipe using a mesh I created (ASCII .stl) of a cylinder using Blender. I read that it is easier to modify a tutorial case than to set up a case from scratch and I also read that the pitzDaily (simpleFoam) example was close enough to the case I am trying to set up. The issue is that I am unsure how to switch from the mesh that the case uses to the mesh I have created. I read that snappyHexMesh is a good way to convert .stl files into a format that openFoam can use and a snappyHexMesh tutorial I read said I had to use blockMesh first but blockMesh is non-parametric and I think when I use it it's targeting the mesh from the tutorial and not my mesh and deleting the blockMeshDict folder gives me an error when I then try to run the blockMesh command. Do I need to convert my .stl files to a blockMeshDict file in some way first? I have 3 .stl files (inlet, outlet, boundary). Thanks in advance
