Upside down spool holder mount(for Ikea Lack)

A holder to easily attach the MK3/S original included spool holder upside down in an enclosure.

I didn't want to screw anything into the top surface of my lack tables, so I decided to make something to attach the original spool holder upside down to the table above.

This will allow you to easily slide the holder in and out when needed. I provided a video below:
 

I used three 5.0x25mm screws to fasten it.

I printed it with:
