Bernina Multiple Spool Holder mounting points

For embroidery my wife sometimes uses the BERNINA Multiple Spool Holder to manage her threads. The holder is attached to the machine using two screw-in mounting points. Recently we needed replacements and this is what we came up with. They are mounted with M4*20 mm Hex Socket Hex Cap screws. Please note supports are enabled as the screw heads are countersunk and this makes for a cleaner hole.
