These RC crawler 3D printed tire inserts are designed to improve the performance of your RC truck. The material doesn’t break down in water or lose its flexibility in cold weather, unlike standard foams and other 3D printed RC tire inserts. Your RC crawler will remain planted over even the toughest terrain.

Our TPU 3D printer filament – rated at 95a – keeps the tire inserts soft and flexible but the inner ring will remain stiff. This allows you to sidewall your rig like never before, whether it’s a 1/10 RC crawler, 1/24, or even 1/6!

:: DIMENSIONS ::

These are 3D printed “foams” or tire inserts for 1.9 RC crawler or scale truck tires. These will fit Krawlers, KM3 and Hyrax 1. 9x 4.75. They may fit other 1.9x4.75. This is for a set of FOUR tire inserts. 

We sell other sizes, as well. See links below for listings of other sizes. 

:: OUR PROCESS::

We’ve been 3D printing since 2017, shortly after 3D printers became readily available. 

Here at PoptartsPrints3D, we custom modify each printer in the shop to enable a new and improved printing process. This allows for higher flow and faster speed to ensure your inserts arrive at your door sooner than others. Due to this process, you’ll never have to worry about layer separation, and each tire insert will have the right amount of flex and a rock-hard sidewall. 

** Thanks to Missouri Scalers for featuring PoptartsPrints3D tire inserts in their 4th Annual Rigs and Coffee RC crawler event! **

:: INSTALLATION ::

Quick and easy to install! Simply put the 3D printed foam insert inside of your existing tire and reassemble the wheel. Feel free to contact us if you have any trouble with installation and we’d be happy to help. No break-in time needed – ready to use right out of the box! You’ll instantly see the difference in your rig’s performance and capabilities. 

:: FEATURES ::

• Won’t break down in water.

• Will hold their shape, even in cold temperatures.

• Soft enough to allow the tires to conform to the shape of the rock the truck is crawling over, while stiff enough to maintain a firm grip during side hilling.

• Do not require regular maintenance, unlike traditional foams. 

• 3D printed on a trusted 95a rated TPU filament.

• Comes in a variety of sizes and softnesses – if you don’t see what you need, message us! 

• Fast shipping and fast response time. 

** These tire inserts are a gamechanger if you’re serious about crawling competitively. Improve your TRAXXAS or Axial RC crawlers’ performance, tackle obstacles like never before, and win competitions! **

Designed by D440 on Cults 3D – if you have your own printer, you can buy the file to support the designer and print on your own.
