I have a few dvds with some missing their cases and was wondering if anyone has tried making their own. The problem with a lot of tutorials is you already buy a basic case to modify that already have the push buttons. From searching online I have found them refereed to as push hubs and spider hubs though there doesn’t seem to be a consistent name for them.
That can be done, but most libraries or maker spaces will not have the tools/equipment. It is a pretty niche corner of 3d printing and is still either very expensive or very DIY. If it makes a difference, most 3d printing is done with PLA which is commercially compostable.
Another option you might try is your local buy nothing or Craigslist. DVD cases aren’t uncommon just yet
