eSun eBox Cover upgrade.

This is my attempt to achieve a better perfomance with the stock filament dryer available. It is aways a struggle to achieve a good drying level living in a tropical country like Brazil, in the coast like Rio de Janeiro. To give some idea, the actual humidity is 70% indoor. 

There is always an immense quantity of vapor adhering to the top of any lid of any dryer - I have the Sunlu and a Sovol. Sometimes I have to open the lid and circulate manually the air so it can keep drying - the water keeps locked from the ambient. 

What I did is make a lid that has an opening at the top so the water can come out. It is not necessary to dismount the original lid. I put a piece of anything that can absorb vapor of water and voila, achieving 15% of ambient dying. I am using a paper cloth, but one can use diapers or a vase with desiccant.

One could not store the filament in there, though. After all, it's open. Dry and out for another storage solution - or, in the case os this dryer specifically, remove the alternative lid and use the original one. 

There is a place to put a generic temp and humidity sensor.
