Nebula RC JConcepts 1.9 Tusk Tire Insert STL Digital File

The Nebula RC JConcepts Tusk 1.9 insert STL digital file gives you everything you need to print professional grade TPU tire inserts for your JConcepts 1.9 Tusk tires at home — no waiting for shipping, no foam degradation, just instant download and print.

What is the Nebula RC JConcepts Tusk 1.9 Insert?

The Nebula RC NoFoam™ JConcepts Tusk 1.9 insert is a precision engineered STL digital file designed specifically for JConcepts 1.9 Tusk tires. Compatible with most standard 1.9 beadlock wheels, this insert fits the most common wheel configurations right out of the box. If you run a particularly narrow or wide beadlock ring, a different size variant may be required — check our fitment guide at nebula-rc.com for details.

Print it at home in TPU filament and install a high performance insert that delivers superior sidewall support, waterproof durability, and tunable firmness that traditional foam inserts simply cannot match.

JConcepts Tusk 1.9 Insert Key Features

Precision Fit for JConcepts 1.9 Tusk Tires — The Nebula RC insert is engineered specifically for the internal dimensions of JConcepts 1.9 Tusk tires. Whether you’re running the standard Tusk, Tusk+ or any other JConcepts 1.9 tire variant, this insert delivers a consistent precise fit that keeps your tires performing at their best on every trail.

Waterproof TPU Construction — Forget foam inserts that absorb water, rot, and lose their shape over time. The Nebula RC JConcepts Tusk 1.9 insert is printed in flexible TPU filament — completely waterproof, rot proof, and performance consistent in any conditions. Run it through mud, streams, and rain without concern.

Tunable Wall Count — Dial in your insert firmness by adjusting wall count during slicing. Increase wall count for a firmer insert on heavier scale builds, or reduce it for a softer more compliant feel on lighter rigs. The same STL file works for a wide range of rig weights and driving styles.

Fits Most Standard 1.9 Wheels — This insert is sized for the most common 1.9 beadlock wheel configurations used in scale RC crawling. Compatible with popular brands including Vanquish, SSD, RC4WD, and most other standard width 1.9 beadlock wheels.

Instant Digital Download — Purchase and download immediately. No waiting for shipping. Start printing your JConcepts Tusk 1.9 inserts the same day you order.

Why Choose Nebula RC Over Foam Inserts for Your JConcepts Tusk Tires?

JConcepts Tusk tires are a serious performance tire used by competitive RC crawlers and trail enthusiasts alike. Pairing them with traditional open cell foam means dealing with water absorption, inconsistent support, and inserts that degrade over time. The Nebula RC NoFoam™ TPU insert solves every one of those problems permanently — waterproof, consistent, tunable, and reprintable any time you need a fresh set.

Recommended Print Settings

Print in TPU filament with a Shore hardness of 90A or lower for optimal performance. TPU85 or TPU87 are our preferred choices for the best balance of flexibility and sidewall support in JConcepts 1.9 Tusk tires. These materials can be challenging to print and may require tuning your printer settings — slow print speeds and a direct drive extruder are recommended for best results with TPU filament.
