The file 'Meraki MR44 / MR46 Ceiling Mount Bracket Adapter Thingy 3D Printer Model' is (stl) file type, size is 22.2KB.
I can't believe nobody has made this yet. In an effort to go 2.5Gbe, I bought an MR46 used on eBay for about $270 (Dec 2023). Price was low due to not having a ceiling bracket.
Problem solved.
EDIT: Don't print in PLA. Fell off my ceiling within 24 hours. xD Re-printed in PETG, made a slight modification in V2 so the clip is always under pressure. Problem solved. Again.
