Ventilation for kitchen drawer

The cupboard under my parents cooktop gets warm, so I made this to help get ventilation and cool everything down.This is a prototype but I belive it is usable. It has good coverage around the hole to hide any accidents. Right now it is 14mm from one side to the other, it might be a bit short on some cupboards, but with glue it shuild be fine. It is possible to change the sizing in bambu studios or (if I did it correctly) open the file in cad to work on it there.I will work on it and add the finished product later on. So far the plan is to give more room for the cupboard to fit, I might do that in the form of adding multiple places for the spheres to attatch. I will increace the sice of the spheres to make it fit better. I will work on how big the filets are, to get nice and rounded corners when printing.If you print it and find anything that can be better, please let me know. This is my first model on here, and the first “propper” thing I made on fusion.
