Hey everyone, I'm Jax and this is my first post. I wanted to know if anyone had any ideas on how to make an stp for my boyfriend that can be put into a packer. I already have some tubing and I'm thinking of using a "pEZ" funnel for the receptacle, but I know that they're kind of bulky and hard to pack with (trust me, I've tried) should I try the baby bottle nipple thing? Or is there some other method I could use that could work well?
