Add new stackable bin generator

[pkochubey]

A regular box that can be stacked on top of each other.

This looks very nice. You might want to consider a variant that has the "h" edges holding the front from the sides for rougher use. Plastic bins often have an additional vertical front wall that serves as a grip and place to put a label: https://www.morplan.com/gb_en/23563 That might also a nice addition.

You are currently using sx and sy as parameters. They allow multiple sections which is currently not supported in the code. Either move more code over from the TypeTray generator or switch to x and y to get a simple tray without inner walls.

You also need something preventing the bins from sliding side to side and then falling off. You can either have strips to be glues underneath or add Stackable Edges to the back wall, too, - or both.

@florianfesti Thx, it's very good suggests. I fix code and image, now tray stable!

[pkochubey]

But now I look at it and understand that the “limiters” can be glued on and it will look even better inside.

For the grip and label piece I was thinking about a cross section like this:

|                       /|
|______________________/

To be fair, this is pretty difficult to see on the photo. This way you can grip the bin from underneath and pull it out. Ofc this requires the sides to extend to support this front piece.

This should be adjustsize(self.h, "s", "S") to adjust for the stackable edges

done

Fully tested 12x12 cm

OK, I added a few more fixes. I was pretty busy last week. So it's easier to just drop the changes now and here.

After agreeing that we are happy with the result the patches should all be squashed into one.

@florianfesti Looks good, thanks

[florianfesti]

OK, squashed most commits. I moved to the build in bottom stabilizers after fixing them. They are a bit shorter to they work with stackable edges all around. They still should be fine here.

[florianfesti]

OK; this has gone on long enough. Thanks for all your work!
