Printed this in sun PLA+ and printed well. The fitting on the lens hood is perfect. The holes for heating up the threaded inserts are a bit small so I ended up making a mess of it, and the inserts filled with plastic. I would advise make the holes slight bigger, like a cone shape from behind so they don’t fill with plastic as they’re melting in. Because I ruined mine, I’m just going to glue the 2 sides together. Less plastic can be used by designing the squares / borders closer to the lens hole opening, but of coursing keeping it square to enable filter mounting points with tape.
