This is a cradle for the sx350 chip. It is designed as it for the 1590b hammond box. If you put the hole for the 510 right in the middle between the back an the lip you won't have to trim the cradle. If it's not center you will have to trim it. Also you may have to trim the opening where the epoxy part goes as they do not put the same amount or even put it in the same place each time.
