Yipetor Frozen Dog Treat Tray Stackable Support

Yipetor and similar brand frozen dog treat holders (like the one linked below) come with a silicone mold for freezing mixtures to use in the toy holders. While they work well, the trays are very flimsy and can be very difficult to insert into a freezer when full without spilling due to how floppy they are, lacking in any rigid supports. I've designed these trays to not only securely hold the trays while filling and transporting them to the freezer, but also to be stackable. The silicone molds are easily removed once the treats are frozen, or left within the stackable tray supports until needed.
