Notch for baseplate click latch #264
Description
Click latches are all the rage at the moment, and I'm working on implementing a design in GridFlock (PR, and if you want to try it, see the generator). The obvious problem with these latches is that they keep the plastic in compression while a bin is in place. This can lead to creep, which is especially bad with PLA.
However with slight changes to the bin, maybe this can be avoided. Consider this edge design:
On the left is the normal bin profile (black). In red, you can see a modified bin profile. It can be printed without supports, and is compatible with standard base plates, but it adds a notch that a special baseplate (green) can latch into. The special baseplate would have some mechanical give to bend when the bin is being inserted, but once it is in place, it goes back into a relaxed state and conforms to the notch on the bin side.
This should reduce creep since the baseplate latch is only stressed for a short time. It might also be more secure than previous click latch designs that rely purely on friction to hold the bin in place.
Do you think this is a viable design? And would you accept a PR to gridfinity extended to add this notch to bins? I can do some mechanical testing and implement the code. If you have any thoughts on the design, that would also be appreciated.
