Project Hail Mary has a free 3D model for print

[Bryan Eckert]

Pretty neat, free 3D model straight from the movie (saw it this weekend, really enjoyed it).

The model is in the Gallery section.

I Completely agree with you Bryan - at least from the pic in the main webpage. I didn't DL the file yet. But, I will do that later today - maybe during my lunch break...

Which has me wondering - I now there are filaments with metal particles in them - and they are typically PLA based. I'd be really curious to know of there is ABS based metal filled filament. Again - I was Pondering this as I was typing this email. So - didn't search it online - as I'm trying to make a Super Quick reply in between Coding tasks at work (you know - trying to "multi-task" - which Humanoids supposedly can NOT efficiently do...). 

If there were ABS based versions - I could vapor smooth the part - to give a cleaner look after removing the Supports...

Anyway - it's Back to the Grindstone for me down here in the Salt Mines...

I think I'll print it in a silk pewter PLA.

That sounds like an Excellent choice. Does it actually have Pewter metal type particles in that filament??

Did you see the movie yet?

I just heard on the news that this movie was the BIGGEST in the Box Office this past weekend!

No, it’s just a metallic silk like the silver, gold, etc. but it’s darker.

I printed this Darth Malgus lightsaber in the pewter:

A good print for SLA... as the supported model indicates per the SLA type of supports applied.

FDM? Not so much.
PS puts supports inside the model making it quite a painful cleanup without soluble support material.

Uncle Jessy printed it on his Kobra Max:

If you rotate it to the right and use slim tree supports on bed only and critical areas only you can get it to print without sticking supports inside.

That's an AWESOME Print Bryan! Such a GEEK Type print!!!

The Movie was also Awesome! Time to Bump Fist me!

I LOVED THIS MOVIE. 👎 I also printed a Grace :D He's printed on my prusa 3.5. I used the supported model so his back looks kinda awful, but the front looks good. ESun bronze silk was pretty much the perfect color for the model.

I'm gonna give a couple of the suggestions you all have made a shot because I was struggling with the whole "no i do not want to fill the entire body with supports, thanks"
