that door is REALLY bothering him,lol
There is a very easy fix to the rattling door problem.
Take thin electric Tape and apply on the sides of the door near the corners.
1 layer at a time until the door won't shut, then take out the last layer.
You'll find that the door stops moving. I learned this fix from an owner of the Cloupor Mini when I posted my problem on another thread.
I found it so annoying on my Cloupor GT 80 that I was about to sell it on the Classifieds when I tried this and it worked.
I'm not good at crafts but I'm sure others can make it look prettier then my attempt.
