I created this adapter for mounting my tp-link Omada Controller OC200 in a server rack. The controller simply snaps into the printed frame without any additional screws or other fixture.
For mounting small parts inside a 19'' rack I use the DAP Audio 2U rack panel with 10 modular segments. This adapter is made for this rack panel and takes over 3 segments. You can buy the rack panel here: https://www.musicstore.de/de_DE/EUR/DAP-2-HE-Rackblende-f-Modulsystem-10-Segmente-MP-1/art-PAH0017160-000
This design was inspired by other modules for this rack panel, including:
I like to use Prusament PETG Galaxy Black for all my segments with infill set to 40% in this case.
