About this model

It could be printed from PLA, PAHT-CF, ABS, or any other strong material.I don’t recommend PETG since it’s a bit flexible, but if you add more perimeters, it can work well too. For stronger materials, fewer perimeters are needed—something like 6.For PLA, I strongly recommend using 12 perimeters.
