An Ikea Skadis tool holder specifically designed for the JR.WHITE Acrylic Paint Pens Paint Markers Set of 18. I printed with Flashforge ASA white filament - its color is a good match to the white Ikea Skadis board.

These holders are mounted with Skadis nut, see details here: https://www.printables.com/model/228663-t-nuts-for-ikea-skadis-pegboards

Needed hardware:

• 2× Printed M2.5 T-Nuts (link above)
• 2× M2.5 DIN934 Hex nuts
• 2× M2.5 × 16mm or M2.5 × 18mm screws
