This is a simple fix for the track/treads of the excellent Killdozer remix by MakerKJS. To be clear, I had nothing to do with the design of this model, I simply repaired one piece of it.
The original model disappeared into the void of Thingiverse, so I've included all of the files needed.

I wanted to print a mini Killdozer, and when I scaled the model down to 50% a thin area of the treads turned into a gap in PrusaSlicer. This fix just gets rid of that thin slice of track.

I would probably recommend you not scale it down to 50% like I did, because some pieces become very thin, and this model requires a ton of supports making post-processing a delicate process. I had to glue a couple pieces back together. Overall, I enjoy how it turned out, although it looks a bit sloppy because scaling it down this much caused some layer artifacts.

I used a couple sample spools from the Paramount3D sampler pack. Egg Yolk Yellow for the Killdozer body, Black for the tracks, and Battleship Gray for the armor plating. Makes a great conversation piece, if the conversation is to be about how you might be a sociopath...
