Nukatap Counterpressure Canning Adapter

I didn't want to buy new gear to make it so I could counterpressure fill cans, so I made this adapter to work with my existing Nukatap Counterpressure Bottle Filler.

Print the 2 pieces and then fill the Mold piece with food grade silicone (yes, you want food grade since it will come in contact with your beverages). 

With Smooth-sil silicone I used about 25g of A and 2.5g of B (so roughly 27.5g of total silicone. I would probably recommend using a bit more just to make it easier to pour but you will have more loss this way as it does take about 25g of silicone total to fill the mold. 

After your silicone is cured, you should be able to just pop it in the Can Cap piece. Remove the other silicone bung from the Nukatap filler and slide your new can filler adapter to the top. 

Updated mold file to have less inner height (inside the can)
