Sorry that it’s taking a while - we’ve been using a new to us manufacturing process for these which has involved a lot of iterations and back and forth with the factory. It’s progressing, though (we’re sending them some fresh design files this week) and I’ve been making sure to bring it up in our weekly dev meeting so it gets kept on our radar.
You’re very welcome to source a case elsewhere if you wish - there’s quite a selection of nice 3D printable options available now: https://www.printables.com/search/models?q=nvme+base
