Original spool holder screwed on table

I was doing the [lack enclosure](https://www.thingiverse.com/thing:3195402) for my Ender 3, but don't have bearings yet to do the roller for the spool.
So decided to screw in the original spool holder on the table, but noticed that it was bending a bit and wasn't too secure, so I made this simple holder on the side to hold it good. I didn't find anything like it (or didn't know what to search for) so decided to make it.

For printing it like in the picture, I just didn't print top and bottom layer, so only the infill shows. It's an easy print.
