Summary

This is the second version of this hood, modeled in Blender. I've printed it on 2 different FDMs. Tested on the 250mm telephoto STM lens, the hood fits nicely. I made the center a bit wider, allowing it to accomodate the lens cap easier and have softened sharp corners.

No supports necessary, it just needs time and PLA filament or resin. I will try resin next, but I expect that PLA is more durable.
