Lack Enclosure Spool Holder for Ender 3

I designed this small adapter to be able to use the Spool Holder that came with my Ender 3, on my Lack Enclosure. It's designed, so that the original Screws can be screwed directly into the adapter.For mounting the adapter with the attached spool holder to the upper Lack Table, I've used some M3 Screws made for wood.
