LS Oil Dipstick Plug Gen 3 5.3 5.7 6.0 LM7 LS1 LQ9

This plugs the dipstick hole in an Gen III LS motor. Should work on Gen 4 as well but I haven't tried it, I just hear they are the same. 

It's common for LS swaps to need the oil dipstick in a different area (usually the oil pan) so if this hole isn't plugged you'll leak oil everywhere when running. 

I would HIGHLY recommend printing this in TPU. I used 72D TPU and printed it on my H2D with the attached print profile. In my experience TPU is very resistant to gas and ethanol, and has enough flexibility to squeeze into the hole while being slightly oversized.
