Overview

I designed this model because we use a lot of mason jars at our house for food storage.  We have a lot of extra lids at different periods of time depending on whether we have a lot in the freezer or not.  Prior to these models, all of our lids were tossed in a drawer and it made it hard to store anything with them and they would slide around.  

Each storage section can hold 7 lids and they can be linked together with their dovetails on the bottom so they don't slide around individually.  For the last one in the link, I used Bambu Studio's cut feature to remove the dovetail tab to make a clean surface on the end.

Printing

I printed these in PLA, but any non-flexible material should work fine.

I suggest using at least 15% infill.

I enabled regular supports to fill in the tail section of the dovetail.  Supports seemed to come off easily.

Happy printing!
