Knocking over a freshly pumped bottle of breast milk sure makes a dad feel terrible. Designed these after spilling a bit.
The attachment point was designed so I could pick and choose where to mount it - wasn't sure where I'd be putting them. These work with the Medela bottles we have, and also have a good friction fit for the Philips Aventi feeding bottles we've got. Works ok on a few other types, although they're too large for the Ameda bottles we have.
These work well so far and have a very snug fit on the Aventi bottles, but I'd like 'em to be a bit tighter on the Medelas.
Second fileset (breastmilkbottleholder6) is much tighter on the Medelas, although a bit too tight on some of our other bottles.
NOT for use to feed babies! At least unless you're also automating burping and infant CPR....
Source file is Google Sketchup. These were made on a Cupcake.
[update - we're still mainly using the revision 4 ones w/Medela bottles. My wife thinks they're fine so I haven't swapped them out, and they've withstood being bumped a few times already. Either model works, use the #6 if #4 is too loose]
