Vertical Sliding Cabinet

No one name fits this build, I'm just going to call it a sliding vertical cabinet on rails. This is my option that will store a drafting board, the drafting tools and two pencil/marker runs in a 4" vertical sliding cabinet. It has a custom lock from mothers old piano parts. When she had tears dragging it out to the road for salvage, i couldn't pass up to make something out of the pulled parts. I have yet to finish the inside pencil and markers holders, my delay is working out the details. I would like each pencil holder (door side) section to be removable. Should have that KZbin video out soon.
