2nd try on demo box

So, we had ourselves a barrier : the 3D printing service can only print at most 20cm X 20cm in size. Our electronic lock itself is already about 19cm, which tells us that we can't print the whole previous design in one shot. What we can do is to print them part by part and combine them together with screws or glue.

So, I gave another shot on how it will sorta look like if we were to go that way. You can get the Sketchup file here : Second Design
