Rootmars is the leader of the Mars people and the creature who plotted the invasion of Earth. It appeared as the primary antagonist in the second and third parts of the Metal Slug video game series. The extraterrestrial villain is also known as “The Mother Brain of Mars people”. The tyrannical leader has never been endowed with any kind of “personality” though is clearly obsessed with a blind desire to conquer Earth or even better, the entire galaxy. But apart from the alien’s cruelty, Rootmars shows high intelligence and is even able to conclude an alliance with the enemy so to increase its winning chances or to recruit a valuable professor to join the army as it happened in Metal Slug Attack game. This Martian’s brain is directly connected to its ship’s core via large cables. Acid spitting, energy balls and electric brainwaves are among the main weapons of the game’s final boss.


The model is saved in STL files, a format supported by most 3D printers

FDM version features:
- Contain 42 parts;
- Assembly kit includes lock One part of  Lock (42_ge_lock_10H(x76)) needs to be printed 76 times. One part of  Lock (41_ge_lock_7S(x2)) needs to be printed twice;.
- Made with a platform so that the model could stand on the surface;
- All parts are divided in such a way that you will print them with the smallest number of support structures.

DLP/SLA version features:
- Same as FDM but smaller, also made as 16 parts;

DLP/SLA Eco version features:
- Same as the DLP/SLA version, but contains parts hollowed out to save resin;

SLS version features:
- Same as SLA but made as 4 parts to save your material;

All STL files for 3D printing have been checked in Netfabb and no errors were shown.

Below you can find printing recommendations for CuraSimplify3D and Slic3r 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.

- 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.
