First time pumping and D.I.Y pump question

Just pumped for the first time!! I will definitely be adding this to my routine. Loved the results. I look forward to having to up-size my pump! I did make my own. Very happy on how it turned out and after the first time using it, I am already making plans for my next one. I didn’t really see much of a gain in length while pumping, but there was definitely a difference in girth. I tried a different method to soften the base each time I used it. I really wasn’t happy with any. What have all you D.I.Y.ers used that you are happy with?

Curious how you made your own pump. Details?

I bought a section of clear tube off of Amazon, a cap and hose fitting at my local hardware store, and a brake bleeding kit at Harbor Freight. I would post a pic, but, I was in a car accident Friday and smashed my phone. I won’t get my replacement until sometime this week.
