I wanted a side panel for the case but couldn't find any good one so I make a mesh side panel that is a 2 piece design so it can fit on more printers than printing on the entire thing.
If the insert is too short then you can just stretch them. Its pretty self explanatory on how its put together. There is some adjustability, you can move it back or forward the entire side panel once its all put together. Reuse the original screws that came with the case.

Supports are 1% for the big side panels that you need to print 2 of them.

3D Printed Mesh:
I set the walls on 2 but you can try and print them without wall to give a nicer look. Remove the top and bottom layers. Use the infill density and infill pattern to customize your mesh.

DIY Mesh:
You will have to cut it down to size. You can 3d print a mesh and use it to have a general Idea of the size. Cut more than you need so you can cut it down to size rather than trying to have the exact size in one go.
