This is an adapter for a chicco diaper can so you can use bigger trash cans. The problem with the original chicco diaper can is, that the volume is very low, so you have to empty it every 1-2 days (happened to us).
You can use the upper part of the chicco diaper can, put it on the adapter and then use a bigger trash can you already have. I also modeled the locking mechanism, the fit is pretty good.
As there are a lot of different trash cans out there, you have to fit the adapter to your own trashcan. Therefore i included the Fusion360- and a Step-File. In Fusion360, change the parameter "trashcan_inside_diameter". You find this under "Design - Modify - Change Parameters"
