Holds 1x Ethernet expansion module and 2x regular expansion modules. Regular expansion modules fit in the Ethernet expansion slot but may move around slightly. Designed to fit inserts that are at least 0.75U tall (at this height, the connector of a 0.75U expansion module will touch the floor of the insert as intended).

Print upside-down without supports. The small stoppers on the bottom will have a rough surface but will still provide enough support to prevent the modules from falling through.

If you need to use a smaller insert, trim the bottom to the desired length using a slicer.
