I am currently new to the modeling world but I want to move to helmets. I have a PRUSA I3 MK3S and I need help on sizing my head and sizing the model for printing. The only slicer software I use is Prusa Slicer. But I would love recommendations and general help. Please and thank you. :)

Using your 3D software of choice, generate a dummy head object with your dimensions and size the helmet model off that.

TinkerCAD is an easy to learn online, simple 3D modeller. You can import 25 MB STL and OBJ files. With your “dummy head object” as Kokanee suggested you can make the helmet transparent and view the interaction to see if the helmet will fit and if there are any problems putting it on.

Most times the helmets you download free or pay for are sized for normal people or are the dimensions of the filming ones, but not always.
Considering it might take 24-48 hours or more to print a sizable piece, you don't want to waste time or materials on the wrong size.

I recommend printing a thin slice of helmet to double check the scaling, before printing the full thing. Also don't forget about the space needed for foam padding and airflow (for both comfort and breathing).

I use Armorsmith Designer! It is great for fitting any kind of stI to your exact measurements.
