CeraVe Pump Lid Adapter

These lotions come in a 2-pack with 1 pump. But strangely (and frustratingly) the jar mouths are different sizes and have different thread profiles, so the pump only fits one of the two jars. I made this adapter so the pump can be attached to either jar.

The inner threads on the adapter can be a bit tricky to line up, as it's a tight fit (and the threads on the jar are kindof bizarre). It's easiest to put the adapter on the jar first, as pictured, and then the pump lid can be twisted on like normal. The inner threads on the adapter only go about halfway through the internal bore; the side without threads should be face-down when putting it on.

I printed it with an outer brim to keep it stuck to the print bed.
