I needed a compact tool holder for the left hand side of printer (no room on the other side), so I opted to design my own. This one holds 3 tools like pliers/etc, 1 bed scraper, 9+3 hex keys. The tool holder attaches to the printer with 2 M3 hex nuts, and replacing the 2 screws for the Z upright with longer ones (to go through the frame into the tool holder) (I used M3x16)
A variant of the design is included if you want the tool holder only for the right hand side
