Gridfinity Skeleton is a baseplate with the goal to use as little filament as possible. Since the baseplate will be generally be placed on a hard flat surface the baseplate does not need to resist bending but rather needs to be strong in the horizontal plane. With that in mind a LOT can be removed from the original design while still holding the bins well.

At only 16 grams for a 5x5 grid it's worth giving a try!

Let me know what you think and if there are requests for certain sizes. I have also included the step files so that it's easier to make improvements on my design.
