Paper Towels and Baking Soda
You will need…

Paper towels, preferably 2-ply
Baking soda (sodium bicarbonate)
¼ cup measuring cup
1 tsp
A clear bowl for mixing
A bowl for dunking
A way of hanging wet paper towel to dry like a clothes drying rack



Mix 1 tsp of baking soda into ¼ cup of water in the clear bowl until the baking soda is completely dissolved.
Allow the baking soda to sit until the water becomes clear. There will be a little baking soda left in the bottom of the bowl that was unable to be incorporated with the water. This is expected, and desirable as it indicates that the water is saturated with baking soda.
Dump the water-baking soda mixture into another bowl trying not to get that left-over baking soda into the bowl.
Set aside the clear mixing bowl and dunk one paper towel into the water-baking soda mixture. Allow the water to soak all the way through the paper towel before removing.
Hang the wet paper towel over something to dry. This can take up to 24 hours.
Once the paper towel is dry, you can separate the 2-ply paper towel into two pieces and then cut them to a similar size as the wadding you are used to.

Assembly is similar to this video:

Material: PLA
Print height: 0.28
Supports: yes ( You will need to carefully remove the support from where the engine sits. Once I got the bottom removed I was able to carefully pry the inner support away from the side wall with a small screwdriver, the support then just fell out from inside as a tube.)

Build plate adhesion: optional. I didn't use any.
