Update (10/25): The new design works amazingly well! It's now two identical pieces, which can be printed in different durometer filament to change how the truck behaves. However, that's not why I changed them. These are split in the middle of the tread, so now they're super easy to print with no supports at all. There's no need to align the two pieces, just make sure the curved side is towards the sidewall of the tire.
Update (10/17/24): I got annoyed with trying to remove supports, so I spent many hours looking at how I can get rid of supports entirely without compromising on some of the features that make this design work so well, and I think I've figured it out, plus added a lot more tuning options. A new design composed of several slices of the insert will be live soon, after I go play on the rocks.
Another note (10/15/24) : I am continuing to develop this design for different applications. I'm happy with how it works on my Vanquish H10 with stock tires (which are amazing for "free") and 24mm 1.9" aluminum wheels, and will now start optimizing for my Wraith (2.2s with 5.5" tall tires), and then my SCX10.3 JLU (1.9s with 4.19" tires). I'll be posting dated updates here. If you see an update about your tire/wheel combination, send me a message.
I've been unhappy with the performance of tire foam and silicone inserts for a while, so I downloaded a few of the existing printed insert designs to try. Unfortunately, I wasn't happy with those, either, so I decided to design my own. I developed this design specifically for the Vanquish H10 I'm building into more of an Ultra4 truck, which means I have to keep speed in mind. This design has a thicker outer ring to fully support the tread of the tire, and symmetrical spokes arranged to create progressive resistance.
NOTE: This insert is designed specifically for the dimensions of the Vanquish H10's stock 4.75" tall tires on 24mm wide 1.9" wheels. If you have different tires or wheels, please send me a message with the dimensions listed under technical information. I will configure one tire height/wheel size combination per order, but I'll work with you on the rest of the parameters so you have exactly the right insert for your truck.
