The case is built of two pieces, one bottom-side and a inner-top part.
This case was 3D printed with a PLA printer at 4mm with 'regular' white PLA.
I would recommend that you use a resin printer for cleaner results.
My printer did have issues with the wall sizes, and a couple of inner supports got broken during the printing process.
To get either the left or right version, you can put them into you slicer of choice and invert the X-axis of the models.
