I made a variation of TheOrginalRis' expansion card holder that can hold one larger sized card like the Ethernet adapter. The lid is a bit looser on this model, but I like it better than the original.

Some people had also asked for a version of the original with the lid and tray as separate models. I've added those in as well, to help people out.

Here's the original description.

Expansion Card Holder for Framework Computer Inc. Laptop Expansion Cards.

Holds up to:

6 expansion cards

6-12 SD Cards when combined w/ Expansion Cards (much more without)

3 SMALL USB Drives

Many MicroSD Cards (Haven't counted the actual amount able to fit)

1-3 Microfiber Cloth's

NOTE: The amount above is based on configuration you choose not all of that will fit at the same time

This is just a prototype but its at the stage where I wanted it to be for my use case. I decided to post it because I was asked for the file a few times.

Lid uses friction to stay in place so tolerances are very important and you may have to adjust that based on your printer.
