Sorry I guess I don’t know how to post an SVG properly. If you right click you can save it.
You can make it out of any thin stock. I used super glue to glue the three layers together being careful not to glue the slide. I don’t know if it was necessary but I also waxed the slide before I put it together.
I used Minwax Paste Finishing wax. It works really great to stop wood parts from sticking, protect machined beds (i.e tablesaws) and for a wood finish too.
If I didn’t have that I would just use candle wax buffed in to make the “drawer” easier to slide.
