Dry-Erase Marker Holder

thingiverse

In many classrooms dry erase boards leave behind sticky residue on the tray that ends up stuck to your hands. Fortunately, most dry erase marker holders can be made inexpensively at home. All you need is a basic whiteboard tray for the holder to function properly (it fits most standard trays). If there were built-in guides within the marker holder it would prevent the markers from slipping and sitting at an angle - although this isn't a major issue. Aside from the slightly crooked markers, this DIY solution worked flawlessly on the first try.
