spark plug skull, a thing.

My test for My new resin printer.

Skull Tank Tracks, not sure what to call it, lol
And yes, I know My painting sucks.

If you are going to print this on FDM printer, then I suggest you try and use some thin wire for the cables on the coil and distributor.

Due to Thingiverse file size restrictions, the part, SparkPlug-Big-All-PARTS-JOINED.stl, is a lower res, there is a higher res one on printables.com.
You are better off downloading the parts separately for a more detailed model.
