This is a simple 4 slot case for extruders. Like every other project on MakerWorld, you can print using whatever materials you want. Nothing about this model is dependant on the material used unless you want the translucent lid.

The translucent PETG was finished by dipping it in MEK, but you can make functionally transparent lids without the need for nasty solvents. Because the outcome is really dependent on your own printer and the context it exists in, I can only provide the included profiles as a starting point.
