Modular Arms for Infernal Engines – Grimdark Sci-Fi

The engine already has a body. What it needs is a way to reach across the table. Modular Arms for Infernal Engines by 3DArtGuy is an October 2026 grimdark-month parts kit: arms and weapons that mount on the Infernal Engine models, and that also kitbash onto demon and chaos mechs in the 180 mm size range. Independent artist. Not a studio weapons sprue. Not designed, produced, or endorsed by anyone who owns the setting.

Parts kit. Modular. Ten weapon options and two arms. Swap one onto an Infernal Engine, or drop it onto another mech that sits around 180 mm. We print them in industrial PVC-like resin so the joints survive the trip.

Why Choose Our Resin Prints?

• Industrial-Grade Printing with High-Detail PVC-Like Resin – Joints, plating, and weapon mounts with virtually invisible layer lines
• Durable & Tough as Nails – High-detail PVC-like resin resists cracking, breaking, and drop damage
• Modular arms – Cannons 1–3, Flail, Giant Cannon, Las Cannon, Melta, Missile, Plasma Cannon, 2 Arms, and a Whip. Built for Infernal Engines, and usable as kitbash parts on demon and chaos mechs in the 180 mm range
• Ready-to-Paint Out of the Box – Cleaned, cured, and support-stripped

Ideal For

• Infernal Engine builds that need a different reach
• Kitbashers working demon and chaos mechs around 180 mm
• Painters who want weapon arms that still read after the primer

Print Quality Options

Choose the perfect resolution for your needs with our high-resolution 3D resin print options. Layer height determines detail and finish: lower microns mean thinner layers for smoother surfaces and finer details, but longer print times and slightly reduced durability. Higher microns balance speed, strength, and cost while maintaining excellent quality for gameplay.

• Tabletop Quality (50 microns) – Ideal for durable, high-resolution 3D resin prints perfect for wargaming and RPGs. Offers sharp details, robust flexibility, and minimal visible layers—great for minis that see real table action without fragility.
• Display Quality (30 microns) – Premium option for ultra-fine, high-resolution 3D resin prints with superior smoothness and intricate details. Best for painting contests, dioramas, or shelf display where maximum visual impact matters most.

Note: Some models only list Tabletop quality due to design complexity or size, but we offer Display (30 microns) as a custom resin print option—contact us for availability and pricing on your order.

Key Specs

• Scale: arms for Infernal Engine models and for kitbash on mechs in the 180 mm range
• Material: High-detail PVC-like resin printed on industrial-grade printers for minimal layer lines and resistance to cracking, breaking, and drop damage

• Processing: We remove around 95% of supports during post-print cleanup, but some may remain to protect delicate parts during shipping or prevent model damage. Models will require sanding (for any minor marks), assembly (if multipart), and painting by the customer—use super glue for assembly (not plastic cement).
• Shipping: Worldwide from Salt Lake City, UT; tracking provided. Typical printing and processing time is 4 weeks (made to order; may vary slightly for large/custom orders).
• Designer: 3DArtGuy
• Compatibility Note: This miniature is an independent artist creation.

It is sold for personal, non-commercial use only and is fully compliant with applicable US copyright and trademark laws.

Pro Tip: One metal for the cannons, then a hotter color in the joints so a swapped arm still reads as part of the engine after the primer. Keep the whip and flail a touch darker than the guns so they do not disappear into the same paint.
