I'd think a couple of pieces of pink (non-conductive) closed cell antistatic foam, one hollowed out a bit with a penknife, would work well. It would both shield from airflow and provide insulation.
The problem is that an LTZ1000 (or LM399) runs hot enough that most plastics you find lying around won't stand up to it for very long (some of them melt almost immediately when you power it up). This is true even of polycarbonate, which is one of the most durable common plastics, and is why the original caps were made from polysulfone.
Unfortunately, it also means that replacements may be hard to make by 3D "printing," since the process depends on melting the base material.
