This is a design to help organize and store 5 inch sanding disks in your workshop.

The grooves are cut with a standard table saw blade width. Depth of the groove should be slightly deeper then 1/8th of an inch. I recommend the spacing of the grooves to be 1 inch apart. One could go even further and do half inch. Pictured is 2 inches and doesn't offer a huge range of flexibility. Cut the grooves first on one sheet before ripping them for the wall. This way it aligns to all three pieces of the wall.

The three walls are cut at 5.25 in wide by however tall you like it to be. I used 1/2 inch plywood but it won't really matter if you use 3/4 as long as the inside width is 5.25. So when you assemble the back wall is sandwiched between the walls. So the inside depth is not as deep as it is wide.

The included STL's is a drawer, Dividers and a organizer for detail sanding sticks that you can find here. https://www.amazon.com/Oskool-Detail-Sanding-sanding-sticks/dp/B08NJ4VRKZ/ref=sr_1_8?dchild=1&keywords=sanding+sticks&qid=1610465212&sr=8-8

The Handles in the project was not an original design. Credit is below to the original designer. The handle I used in my photograph was the Medium. I included a large in case. Anyone wants to go larger. https://www.thingiverse.com/thing:4619895
