[BaBo duo] top lid module bins

I am a huge fan of the BaBo duo organizer system by @Willi. When he posted the bin module for the BaBo system I asked to modify it for the BaBo duo. This is the result. It continues within the standards for the system established by @Willi and he OK'd me to post this. 

I give full attribution to @Willi's genius in the system he designed.

Printing this, you will need to determine the bin depth and if you want one or two. Print a lid plate for each bin and the appropriate bin. If you choose the bin 60, you will need to print one back 30 per bin and replace the back in the next layer down. If you choose the bin 90, you will need to print two back 30 per bin and replace the backs in the next two layers down.
