ABOUT THIS 3D MODELREX is a Metal Gear prototype that was designed as a nuclear-capable bipedal tank reinforced with near-impenetrable compound armour. The all-terrain battle mecha comes from the Metal Gear series of action stealth video games by the legendary Hideo Kojima.Metal Gear Rex model for 3D printing was brought to you by our contributing 3D artist who has been enthusiastic about the unusual bipedal tank and the Metal Gear franchise on the whole for quite a while now. The bulky 3D printing walking battle tank is heavily armed with rotary cannons, anti-tank missiles, a free-electron laser cannon, and a powerful magnetic rail gun. Inside the cockpit of the mecha defence machine, you will also find a miniature of its pilot, the Big Boss, who together with the REX will make for an impressive addition to any Metal Gear display!ADAPTATION FOR 3D PRINTINGMetal Gear REX for 3D printing is an active assembly model and its moderation and adaptation for different types of 3D printers took the Gambody team 45 hours in total. For you to receive the cleanest 3D printing result possible and to minimize the amount of filament needed for generated support the bipedal tank model was divided into many assembly parts, and special mechanisms were introduced into all model’s movable elements to give you an opportunity to display REX in a variety of positions and scenes.All assembly parts are provided in STL files in recommended positions that were worked out in order to ensure the smoothness of the details’ surfaces after printing and that the 3D printing beginners won't face difficulties when placing the parts on a build plate. When downloading any model's file you will also receive "Assembly Manual" for FFF/FDM 1.0 and DLP/SLA/SLS 1.0 versions in PDF format. We highly recommend that you get acquainted with the “Assembly video” and "Assembly Manual" before getting down to the Metal Gear REX model.The model 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 model's scale was calculated from the approximate height of the Metal Gear REX which is 13000 mm. The 3D printing model's chosen scale is 1:32 for the FFF/FDM version and 1:64 for the DLP/SLA/SLS version.VERSIONS' SPECIFICATIONSFFF/FDM 1.0 version features:- Contains 166 parts;- A printed model is 408 mm tall, 394 mm wide, 510 mm deep;- REX’s beak-like cockpit opens to reveal a highly detailed interior and Big Boss behind the controls;- There is a spot inside REX’s head where you can hide the battery and LED wiring and light up the cockpit and forward-facing missiles;- 360° movement of the head and body is ensured by an extendable double ratchet mechanism in the “neck”, and a ball joint;- Opening hatches on the body and legs reveal missiles;- Double ball joint mechanism with tightening nut allows 360° rotation of the shoulders;- Ball joint mechanism with tightening nut allows the rotation of the hip;- 360° rotation of the leg armour via ball joint mechanism with tightening nut;- The pelvis laser cannon can be articulated via a ratchet;- The “shins” are retractable, there are stoppers inside the retractable shins and tightening screws for rigidity adjustment;- The “knee” can go up via a ratchet and it can be fixed in a raised position;- 360° rotation of the feet via ball joint mechanism with tightening nut;- The driving stakes (claws) are articulated;- Rear stabilisation controls (heels) are articulated via two ratchets and can be fully folded;- REX’s assembly requires additional "pins" that can be made out of short pieces of regular 1.75mm filament;- All parts are divided in such a way that you will print them with the smallest number of support structures.DLP/SLA 1.0 version features:- Contains 54 parts;- A printed model is 204 mm tall, 197 mm wide, 255 mm deep;- REX’s beak-like cockpit opens to reveal Big Boss behind the controls;- There is a spot inside REX’s head where you can hide the battery and LED wiring and light up the cockpit;- Opening hatches on the body and legs reveal missiles;- REX’s neck, shoulders, hips, pelvis laser, leg armour, driving stakes (claws), feet, and rear stabilisation controls (heels), move via simple cylinder connectors;- REX’s assembly requires additional "pins" that can be made out of short pieces of a regular paperclip;- All parts are divided in such a way to fit the build plates and to ensure that support structures are generated where needed.You can get the model of Metal Gear REX for 3D Printing immediately after the purchase!

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.QualityLayer Height: 0.12 mm (you can also set Layer Height at 0.16 or 0.2mm for 0.4mm nozzles)Initial Layer Height: 0.2 mm (carefully level the print bed and keep your Initial Layer Height the same as the main Layer Height)Line Width: 0.4 mmWall Line Width: 0.4 mmOuter Wall Line Width: 0.4 mmInner Wall(s) Line Width: 0.4 mmTop/Bottom Line Width: 0.4 mmInfill Line Width: 0.4 mmSkirt/Brim Line Width: 0.4 mmSupport Line Width: 0.4 mmInitial Layer Line Width: 100%Shell Wall Thickness: 0.8 mmWall Line Count: 2Outer Wall Wipe Distance: 0.3 mmTop Surface Skin Layers: 0Top/Bottom Thickness: 0.6 mmTop Thickness: 0.6 mmTop Layers: 5Bottom Thickness: 0.6 mmBottom Layers: 5Initial Bottom Layers: 5Top/Bottom Pattern: LinesBottom Pattern Initial Layer: LinesTop/Bottom Line Directions: [ ]Outer Wall Inset: 0 mmOptimize Wall Printing Order: CheckCompensate Wall Overlaps: CheckCompensate Inner Wall Overlaps: CheckMinimum Wall Flow: 0%Fill Gaps Between Walls: EverywhereFilter Out Tiny Gaps: CheckHorizontal Expansion: 0 mmInitial Layer Horizontal Expansion: 0 mmHole horizontal expansion: 0Z Seam Alignment: User SpecifiedZ Seam Position: BackZ Seam X: Average length of your printer’s plate (e.g.”150” if your plate is 300mm on the X-axis)Z Seam Y: A value higher than the length of your plate on the Y-axis (e.g. 700)Seam Corner Preference: Hide SeamExtra Skin Wall Count: 1Skin Overlap Percentage: 10%Skin Overlap 0.04 mmInfill Infill Density: 20% (for all smaller parts and for all parts of connectors use 100% Infill)Infill Pattern: TrianglesConnect Infill Lines: CheckInfill Line Directions: [ ]Infill X Offset: 0 mmInfill Y Offset: 0 mmInfill Line Multiplier: 1Extra Infill Wall Count: 0Infill Overlap Percentage: 10-20%Infill Overlap: 0.04 mmSkin Overlap Percentage: 5%Skin Overlap: 0.02 mmInfill Wipe Distance: 0 mmInfill Layer Thickness: 0.24 mmGradual Infill Steps: 0Infill Before Walls: CheckMinimum Infill Area: 0 mm2Skin Removal Width: 0.8 mmTop Skin Removal Width: 0.8 mmBottom Skin Removal Width: 0.8 mmSkin Expand Distance: 0.8Top Skin Expand Distance: 0.8Bottom Skin Expand Distance: 0.8Maximum Skin Angle for Expansion: 90˚Minimum Skin Width for Expansion: 0.0Skin Edge Support Thickness: 0Skin Edge Support Layers: 0Material Initial Layer Flow: 100%Printing Temperature: See your filament settingsInitial Printing Temperature: Your filament settingsFinal Printing Temperature: Your filament settingsBuild Plate Temperature: Your filament settingsBuild Plate Temperature Initial Layer: Your filament settings + 5°Flow: 100% (Important!

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.
