I made these out of scrap wood. Often, I've made a project on the M1 and need to lift the material as I paint edging. These are customizable sizing. There's 1/2 inch spacing of notches to let you set the size to what you need. These are sized to be made out of 3mm stock. The file has the top-notched and bottom-notched sizes. and the working parts over to the side if you need to adjust notch sizing for you stock material.
Arrange the cut files over your leftover scraps and cut as many as needed.
The stands can be arranged in any configuration needed to support your project material. stand pieces can be chained in as many as needed.
Hope this is a useful tool for you.
