I love my Python AMS with the Enclosure.  I added two PolyDryers and its even better.

However, after a couple of months, I noticed that the dryers were distorting the front acrylic, making the lid fit less precisely.  

I made this small bracket to mount on the front of the enclosure to firm it up.  It works great.

You need to replace the three M3x12mm screw with M3x16mm. 

It's a half hour print, and a five minute installation.

Enjoy!
