Abrams X US 4th-Gen Main Battle Tank 1/35 Scale

📢 Updated on January 5, 2026: I’ve added alignment pins to the tank body and turret, and also created a new AMS-compatible 3D print profile.

I introduced a lot of new features in the tank’s running gear. At first, I tried to modify my previous M1A1 Abrams model, but it turned out to be more complicated than expected. So I scrapped everything and started from scratch — the whole process took me about a month.

Compared with my previous works, this tank features the following new designs:

1. The side skirts use a snap-fit design, allowing them to be opened freely — you’ll no longer have to worry about weak glue joints.

    

2. The wheels are movable and connected using small C-shaped components. Special thanks to @McCanic for providing the idea.

    

3. It uses a torsion bar suspension system. The suspension is functional, but because of material limitations, I don’t recommend twisting it too often.

📋 Recommended Print Settings (For Best Results) 

• Filament: PLA. Different materials have different shrink rates, so using other filaments might cause fitting issues or dimensional errors during assembly. 
• Slicer: Bambu Studio. I recommend using my default profile — I’ve tuned it specifically for this model. 
• Ambient Temperature: If you’re using an open-frame printer like the A1 or A1 Mini, keep your room above 20°C (68°F) to prevent warping. 
• Print Bed Preparation: Wash with soap and water, then dry thoroughly to ensure good adhesion. For small parts, apply a glue stick for better bed adhesion. 

🔧 Assembly Diagram Notes 

• Blue Lines: Require super glue for assembly. I use Gorilla Super Glue. 
• Yellow Lines: These are moving parts. Do not apply glue here.
