I've designed a holder to attach the dock to IKEA Skadis board.
After importing the file, lay it flat on the side so that the hooks are parallel to the print bed. Make a copy and mirror it over the Z so you have a pair of holders.
Printer: Ender 3 V2
Material: PLA
Layer: 0.2mm
Infill: 15%
Perimeters: 3
Top/bottom layers: 3
Supports: yes, under the hooks
