Remix of Ender 3 - Tools Holder by skmiedg, adapting the attachment to Longer Lk5 top rail. Due to the diagonal supports the external attachment of the original won't match, so I made one that slips inside the rail on the two sides of the screw, replacing the endcap.

FreeCAD source included, but don't hold your breath - the original is stil an STL mesh; the most "parametric thing" you can use it for is the attachment bars, to attach something else in place of that tool holder.

Lay on the side with the author's name. Use supports under the rail insert.
