I just built 3 sustainer cabinets using the TSO plans. I'm using the SYS AZ drawer sliders to place the sustainers in the cabinets. My question is this. Is there a program that you can put the dimensions of your cabinet and the dimensions of your sustainers to get the best utilization fit of your sustainers(or type of sustainer like entering SYS3 M 112)? I tried searching this section but gave up after the 10th page. Any help or suggestions would be appreciated.
