Helmet 3D printing 48H with Elegoo Neptune 3 Plus

Hello, so lately i got used Neptune 3 Plus, i am very happy with it, did some small peints like Witcher wolfe school medallion, but my dream was always to do some helmets, werable of course, but when i decided to finally make one (you know for years i was amazed by making them so did a lot of reserch, sanding, painting etc), but reality hitted hard and i don't know how to do it. I mean i know just, i don't know how to make it fast. I need to make one around 2 days of work, but i don't know if that's even possible. I need advice on:

• layer height
• wall thickness
• infil (% and type)
• speed
• support (density, branch angle [also tree or normal], angle, etc.)

My plan was to make helldivers 2 helmet.

Would be really thankfull if someone had data, you know, numbers, because i don't truat myselfe nor i trust chat GPT and not related post, as every situation is diffrent, and i really really don't want to mess this up.

Thank you all for your time, and God bless.
