Master Chief STL files for 3D Printing | Assembly Model

ABOUT THIS 3D MODEL

Master chief petty officer John 117 or simply Master Chief is the super soldier, the protagonist of the Halo franchise. During the first six years of his life, John lived with his parents on the human colony planet Eridanus II. But after the boy was conscripted into the military service John’s life and personality changed drastically. He became the SPARTAN-II Program recruit and later the soldier in the UNSC Naval Special Warfare Command. With over 30 years of military service experience, Master Chief is one of the most renowned war veterans. 

ADAPTATION FOR 3D PRINTING

Master Chief 3D printing design is a static assembly model. The model’s cutting was chosen by our team to minimise the amount of generated support and some of the parts were hollowed out for you to save resin in the Eco version. In order to conceal the places where the assembly parts of the model are connected, Master Chief was cut along the contour of his armour. For you to achieve the cleanest 3D printed result, the character’s head, arms, legs, weapons etc. are provided as separate assembly parts.

All assembly parts of the FFF/FDM versions come in STL files in recommended positions that were worked out in order to ensure the smoothness of the details’ surfaces after printing and so that the 3D printing beginners won't face difficulties when placing the parts on a build plate.

The design is saved in STL files, a format supported by most 3D printers. All STL files for 3D printing have been checked in Netfabb and no errors were shown.

The 3D printing design's chosen scales are 1:8 for the FFF/FDM version and 1:16 for the DLP/SLA/SLS versions.

Generic

Below you can find printing recommendations for Cura, Simplify3D, Slic3r and PrusaSlicer software.

Cura printing recommendations:

These are basic settings that were tested in Cura 4.8.0 slicer. 

The test models were printed on Ultimaker 2, Creality Ender 3, Creality CR-10S Pro V2, Anycubic I3 Mega, Anycubic I3 MegaS 3D printers with PLA and PETG filaments.

Disclaimer: The following printing settings are a recommendation, not an obligation. The parameters can vary depending on the peculiarities of your 3D printer, the material you use and especially the particular assembly part at hand. Each part that any model comprises often needs preliminary review and you are free to tweak the settings the way you find suitable.

Note:- You can scale up the model (downscaling is not recommended!);- All connectors should be printed at 100% Infill;- For all parts of locks (“ge_lock” in “Source files”) you need to change "Brim" type to "Skirt" in Build Plate Adhesion section.

Slic3r printing recommendations:

These basic 3D printing settings recommendations for beginners were tested in Slic3r 1.3.0 software. Test models were printed on Ultimaker 2, Creality Ender 3, Creality Cr-10S pro v2, Anycubic I3 Mega, Anycubic I3 MegaS, Anycubic Vyper with PLA and PetG filaments. Note:

- You can upscale your 3D printing models. Downscaling is not recommended - it can make smaller parts of the model unprintable, distort the model’s level of detail and result in assembly issues. - All connectors should be printed at 100% Infill.- When printing Lock connectors, we recommend setting the “Brim width” parameter to 0 in the "Skirt and Brim" print settings. In that way, the Locks will be 3D printed with a Skirt only.
