I had multiple prints of this tray in use for several months but got a little annoyed by the hook design. The hooks are very low (to be printable without supports) which can cause the tray to bend down. As the hooks don't sit flush with the back of th tray, this effect is even more visible. That is why I added custom designed delta hooks (3 hooks) which require supports to print but offer a way more joyful and sturdy experience. The hooks are design to have extremly low tolerances with the back of the board so that they do not wiggle or come lose once installed.
The model's form is susceptible to warping. Ensuring a clean print bed with superior adhesion is essential. If you continue to experience warping, or if you prefer to be cautious, consider using the print profile that includes adhesion discs.
