Medela breast milk pump direct to Dr.Brown bottle adapter

It's a bit of a hassle pumping milk to a fitting bottle but then feeding from Dr.Brown bottles for no reason at all and the ones sold on amazon come with those silly half threads that keep falling off if you bump them wrong. There's nothing worse than pumping at 3am and then spilling a whole bottle of fresh milk because of the silly threads.

My design is very simple and tailored for FDM printers. No supports needed just make sure your printer is stable and you have the small neck on the print surface like in the pictures.

I did mine in highest resolution a 0.4nozzle can do at 0.08mm layer height and it came out flawless, but really up to you, should work at any.
