Action Mecha Base 5 for Gunpla Gundam HG RG MG

!UPDATE 15.05.2026 I have added Parametric Arm Trusses!

Finally, print your own Action Base in different colors and match them perfectly to your Mobile Suits for the ultimate custom display!

Print Profiles & Tolerances I have created two different print profiles to ensure the best fit for your setup:

• Tight Profile: Highly recommended if you are printing with PETG.
• Loose Profile: Recommended if you are printing with PLA.

Note: The perfect fit always depends on your individual filament. Different brands and colors can vary slightly in shrinkage and extrusion.

What's on the Print Plates? Both print profiles are organized into the following ready-to-print plates:

• AIO Plate: All-in-One (Everything you need for one complete stand) Print Time: ~ 2,5-3,5h Filament Usage ~ 55g
• Single Arm Config: Arms only
• Double Arm Config: Arms only
• Base + Base Connector: Just the bottom platform
• Adapters & Connectors: All small connection parts separately for quick re-prints

Included Parts in this Design:

• Hexagon Base Plate
• Base Connectors (to link multiple bases together)
• Arm Segments (Pivot Arms & Snap Arms)
• Gears & Stoppers (for the angle adjustments)
• Various Adapters (3mm peg, 5mm peg, etc., for different Gunpla grades)

 Important Disclaimer for the Best Quality: Since this model relies on mechanical snap-fits and moving gears, please make sure to:

1. Always calibrate your printer / flow rate.
2. Clean your build plate thoroughly.
3. DRY YOUR FILAMENT! (This makes a huge difference for snap-fits).

Assembly Guide :

Some Parts should be glued for better fitting, i recomment gluing at least the Arm Truss, and the Double Mount Connector with The small cylinder with the square mount
