Dr. Brown Bottle Cap Replacement

I created this cap replacement because bottle caps for my son's bottles kept dissapearing. I looked online for a replacement stl and couldn't find it. So since I had a modeling software I figured I'd tinker around a bit. Came up with a design that seems to work just fine. I printed mine in PETG with a .2mm layer height and .4mm nozzle at 30mm/s.

I'm hoping there's other people out there who could use this and have been looking like I have. Figured it's the least I could contribute having downloaded so many files from here.

If you do end up making this, please shoot a few photos and post a make. I'd love to see people getting use out of this.
