Marker holder

My wife got a few sets of Twinmarkers for Christmas. They came in a bag which was very messy, so I made her a holder. Each holder holds 25 markers and is stackable. Each hole is 16.5x16.5mm so I'm sure other brands will fit. You can fit 4 holders on 1 plate (X/P series). 5x2 holder: https://makerworld.com/en/models/1086805#profileId-10797305x6 holder: https://makerworld.com/en/models/1087156#profileId-10800817x6 holder: https://makerworld.com/en/models/1086773#profileId-1
