This toolholder will directly attach around the lack leg. It is tight enought to stay in place (beware of scratches if you do not apply proper sanding).
Vertical honeycombs instead of solid walls spare about half of the original plastic (but increase the print time).
The design is compatible with original design accessories, and other remixes (screwdrivers holders...)
Print
Print files for PETG, but I guess PLA is fine (I wanted the same colour as the enclosure PETG parts).
0.3mm layer height (0.2mm doubles the print time!)
Vertical honeycomb may lead to print fails, but I had none.
Post-print
Loads of stringing due to the high number of bridges (vertical honeycomb - PET doesn't help! PLA may be better). You can remove them with a heatgun.
Sanding is needed to fit perfectly to the table leg. If it's too tight you will damage the leg coating: scratches are highly visible on coloured lack tables.
