This is a remix of Chipp Walters Gridfinity Modular Drawer System. I created a special peg for the peg board and added slots to the back of the case, this allows you to slide the caes on and off the Multiboard easily.
*** Update 2024.01.18 ***
Updated the Peg-Slide-Slim stl file to be a little thicker on the bottom so it adds more contact to the case.
