I created a drawer to attach to Multiboard.io. I needed mine to hold the Bambu tools, but it could be used on any standard HSW.
Dimensions of the drawer are: 130mm x 63mm x 49mm tall.
Cabinet mounts to 2 pegs and spans 5 “octo” slots within the same row (Mounts to 2 outer slots, 3 empty in between).
Feel free to reach out for any modifications or custom sizes!
