The original claims not to need support. While I guess this is technically true, you can see how that ends up in the picture here. I tried to improve upon it in this remix, although it's very far from perfect... In fact, without support, the original actually prints a bit better than mine. But if you want to use support, mine should require substantially less than the original. I don't think it will impact function, but let me know if it does.

This object will need to withstand repetitive bending stresses. PET works pretty well for that. I went with the more modern thought that number of perimeters + line thickness is substantially more important than infill percentage. Printed with 4 perimeters and 130% lines.
