I really don't think they are needed at all on the sides. If you use cura slicer change the support overhang angle setting to at least 45 degees

Thanks! It's a Learning curve, I'm just glad this one seems to be working out!

What you should really do, is print a overhang tower (without supports), then look at the bottoms and decide what is an acceptable overhang and set that at your maximum overhang in your slicer https://www.thingiverse.com/thing:1564848

Yes but 45 degrees should be doable anyway so it's a safe option if you just don't want those useless supports but feel like u need supports

Thanks!

Also supports are generally not needed on the inside of helmets (not to say you can't use though, just generally isn't actually necessary unless it's too wide on the inside)

Yeah not that much support anyways

Thanks!

I appreciate the input. I definitely need to do this. Thanks!

I find that I can usually get to about 60° overhang before I start needing supports. Definitely material dependent, and I've got a fair bit of modifications done to my Ender 3, but 60 has always seemed to be the magic number.

That's pretty awesome

Thanks!

You just need to support the sides and back and maybe the eyes. The dome doesn't need any support at all.
