I made another paddle set that have smaller (and more) paddles.
These things dig like crazy and throw sand / gravel 25-30 feet!
Another longer slow motion video in fine sand.

My son wanted some monster paddle tires for his Rustler 4x4 and 4x2 trucks, so I designed and printed him a set. It was my first time printing with TPU, and I printed these with zero retraction - which left a BUNCH of boogers/zits/drips all over the tires. But now that he has a set, I am trying it again with 3mm retraction and 1.5mm glide. IF it works out better, I'll update the post here.
Also, the rims take ~7 hours each - they are made from Hatchbox PLA. And they definitely need support.

It's pretty beefy, but I'd rather it be a bit heavy than have it break. My first iterations with lower density and perimeters failed spectacularly and I don't want it to happen again.
The paddle sleeves take ~13 hours each. They do not need support.

I used thick superglue to bond the paddle sleeve to the rim, and man - it works great!
