I saw a need at work to for a better way to store and display drum sander sandpaper rolls. They are an awkward thing to display in a tidy fashion because there are so many different lengths and grits.
I made four of these bins. Each is approximately 800mm x 350mm x 200mm. They will sit side by side for a total width of around 3200mm.
I designed and cut all the relevant pieces using my CNC machine: Four fronts, four backs, eight sides and 36 dividers using MDF in 18mm, 12mm and 3mm. I cut the base panels in 12mm MDF on my table saw.
