Inspired by this remix, I made some mudguards from scratch making sure there is absolutely no rubbing. My tt02 has various suspension modifications to improve suspension travel, I needed more clearance than normal. (It should work with standard suspension too.) The fender design works with up to 68mm diameter wheels, and significantly reduced the amount of dirt that got into the chassis.
Printed the frame pieces from PETG, the fenders are 30D TPU for durability.
