These clips are designed for 1/4 inch material such as PVC (what I used in the picture) or wood. With the stock models the PVC should be about 2 3/4 inches tall and the length of your drawer. However, if you would like taller dividers you can just stretch the clips in your slicer to the appropriate height.

If you found this design useful, feel free to donate what you think it is worth to my PayPal to cover the time spent designing.
