Sunlu SP2 Front Switch

Sunlu SP2 front switch.
I saw the project by @jakadels where he moved the switches from the Bambulab printers to the front. 
Since I had the same problem with my Sunlu SP2 dryer, I built a similar system here.

Easy to print and assemble.

Please note, I do not recommend PLA, as this is a dryer. 

So use PETG at least.

As a side note, the whole thing is designed so that the switch works when there is a weight on top of it to prevent it from using too much filament.
So when testing, always place the drying box on top.
