No supports are needed for vorpal the hexapod. There will be a few drips inside the cap but they are generally easy to remove, don't show on the outside, and you'll waste far more plastic on a support than is worth it. There may be a drip here or there where there are some bridges but again, not worth the time and plastic to use supports.
Max the megapod has one built-in support in the cap. This was necessary because of how the parts are split up.
None of our other projects need supports.
