These are storage bin dividers for the Hart storage system 21" box. The bins are a little too large for the stuff I needed to add, so I made inserts to split them in half. The pictures don't really show it, but the bin dividers go to the top so the parts don't get all mixed up when you close the case. I printed these on my X1C. 2 bins take about 2 hours to print. One file has a mirrored pair ang the other file has 5 mirrored pairs. The other files are the individual dividers so you can print what you want.
