Medela Bottle Nipple Ring

thingiverse

This is a direct replacement for the yellow ring that holds the silicone nipple on a Medela brand bottle. It's almost identical, but the top surface is optimized for printing the part upside down (it's flat). Unfortunately, that means the clear covers don't have a place to snap on over the nipple. UPDATE 2017-09-14: By request I have added a 'beefy' version with walls 1.5 mm thicker, as well as the STEP file for the original in case you want to make your own mods. Instructions Print in ABS, tglase, Nylon, or another high-temperature material at 100% infill, so that you can sterilize it in hot water and not fill the walls up with water. The milk doesn't actually come in contact with this part, but the baby's mouth might.
