Best first downloads

If you want the cleanest starting point, begin with the official Rocky ZIP, the Sketchfab visualization of the official Rocky model, and the Printables or MakerWorld versions that have real makes, comments and print notes. For a simpler print, choose the Hail Mary spaceship or the keychain before attempting a posable Rocky.
Rocky models: what to check before printing
Source: Image source: MakerWorld / 3DGO model preview, Yolky Filament
Rocky models are the most interesting Project Hail Mary prints, but they are also the easiest to fail. The body shape, legs, joints and optional accessories create many overhangs and small contact areas. For articulated Rocky models, read the file names carefully because creators often specify the number of copies per limb or hand part.
- PLA: use enough walls or perimeters because thin joints can loosen or snap.
- PETG or ASA: expect stronger functional parts, but tune supports carefully.
- Resin: use pre-supported files when available and avoid brittle resin for thin legs.
- Multipart assemblies: dry-fit all joints before gluing or heat-forming accessories.
Grace figurine models

The Grace figurine is usually a better first character print than Rocky because it has fewer articulated parts. The Xenonite-style versions can still need careful support removal, especially around the raised hand and surface detail. The PageMaster MakerWorld version notes that supports were already tweaked, so do not blindly add automatic supports without checking the creator’s instructions.
Hail Mary spaceship STL files

The spaceship models are generally easier than a posable Rocky, especially if you print them larger. Small Hail Mary ship prints can lose panel details and can suffer from visible support scars around engine pods. If the model includes a 3MF profile, open it before importing the STL manually because it may contain the intended scale, orientation and support logic.

The CAD-style preview is useful before download because it shows the model shape without painted or staged photography. Check whether the hull, engine pods and stand are split into separate parts. Split parts are usually easier to orient and cleaner to finish on both FDM and resin printers.
License warning for Project Hail Mary STL files
Many files are fan-made, remixed, re-uploaded, or based on official campaign files. A free download does not automatically mean commercial use is allowed. Before selling printed copies, check three things: the creator license, the original model license and the Project Hail Mary intellectual-property context.
❝ For this topic, the most important rule is simple: download from the original source page, save the license text with the STL, and do not assume that fan art or official campaign files can be sold commercially. ❞
Recommended printing order
Source: Image source: MakerWorld / 3DGO model preview, Yolky Filament
- Start easy: Project Hail Mary keychain, mission patch, magnet or bookmark.
- Then print a ship: choose the Hail Mary spaceship model and test the scale.
- Then print Grace: use supported files if available and remove supports slowly.
- Finally print Rocky: choose a proven version with real print photos and assembly notes.
The articulated Rocky is the showpiece, but it should not be the first test print unless you already know your printer handles small joints and support cleanup well.

A static Rocky desk model is usually more reliable than a fully articulated print. It is a good compromise if you want a recognizable Project Hail Mary display piece without tuning moving joints, sockets or tension-fit parts.

FAQ
Is there an official Project Hail Mary STL file?
Yes. The official campaign made downloadable Project Hail Mary 3D printer files available, including Rocky and the Grace figurine. Because campaign pages can change, use the official site first and keep a copy of the license information with your downloaded ZIP or STL.
Which Project Hail Mary model should I print first?
Start with a keychain, magnet or spaceship model. Print Rocky after you are comfortable with supports, multipart assembly and fragile joints.
Is Rocky better on FDM or resin?
Resin captures detail better, but FDM can work for larger articulated versions if the model was designed for filament printing. PETG or ASA can be better than PLA for functional joints, while PLA is easier for simple display pieces.
Can I sell printed Rocky or Grace figures?
Do not sell printed copies unless the exact model license and the underlying Project Hail Mary rights allow commercial use. Many free downloads are personal-use, non-commercial or remix-restricted.
Why do some Project Hail Mary downloads include 3MF instead of only STL?
3MF files can preserve scale, orientation, color assignments and slicer settings. If a creator provides both STL and 3MF, open the 3MF first to understand the intended setup.
Final pick
For most makers, the best path is: download the official Rocky ZIP or a well-documented MakerWorld/Printables remix, print the Hail Mary spaceship as a quick display model, and only then attempt the articulated Rocky. The Project Hail Mary community is moving fast, so revisit the source links regularly for updated versions, repaired meshes and new print profiles.
