Rackmate T2

I am trying to build a cluster of framework desktops. To accommodate for some other additions and to allow flexibility to scale, I’ve purchased a Rackmate T2, which has a depth of 10 inches. The Deskpi Mini ITX shelves that I purchased off the framework website are designed for the Rackmate T1, which has a depth of ~7 inches, so these shelves just hang on on the side that should be supported by the provided brackets– it cannot reach the brackets as they are three inches away. Are there any adapters or brackets that extend further? Or has anyone created a 3d printed solution for this?
