5x5x6U (5+1) Gridfinity Rugged Storage Box with stowing stacking latches

TL;DR Use my stacking latch, offset or not, for no-interference stacking of 6U boxes.

Using Gridfinity Generator at https://gridfinity.perplexinglabs.com/pr/gridfinity-rugged-box/0/0, which I believe is based on bulbasaur0's work, I generated a 6U (5+1) 5x5 box. Oddly enough 6U total is the default size when I visit the site.

I then realized that the side stacking latches don't stow away like they can on taller unit boxes due to the missing stowing screw design; they flop around and get in the way when not engaged. After hacking off the parts I needed to restore this function from the original work's infill modifier file I then realized that the provided stacking latches interfere with each other when a 6U box is sandwiched between other stacking latch boxes.

So I took the time to iterate a shortened side latch with sufficient access and leverage to both deploy and detach. There are two versions, one that offsets the groove slightly. Both function but I found the offset slightly easier to manipulate whilst in the problem configuration (above box's latch engaged, lower box's latch stowed). Could just be variation between install points on my test boxes, so pick your poison. It might take a bit of fingernail or a pry tool to get between the latches, but at least it fulfilled my needs. I was afraid of opening up more space for access at risk of further weakening the stacking latches.

Choosing to use my shortened stacking latch does mean that every latch in your system needs to be these shortened latches in order to be fully cross compatible. Of course you can always stick with the original stacking latches if you always know where your 6U boxes are going to be in a stack of other boxes. My restless box syndrome could never allow that of course.

I printed mine out of PETG with 3 walls and variable infill. I'd probably go with 100% infill if you care about strength since the latch is a cut down version with reduced material present and a wasp waist around where the load bearing section is. Probably not advisable to be putting the weight of an 18U box full of screws on these, for example. You do you though.

I also generated a slightly shorter handle that plays nicer with 6U boxes; it'll allow the box to sit flat without the handle sticking out at an angle. There is a bit of interference from the label area's bottom lip though.

There's a 3mf file with most everything needed to print a (5+1)U box. It's just missing a clip or draw latch of your choice. I'd go with the shortened draw latch made by artofdecks. As can be deduced from the name it better fits 6U boxes by allowing non-gridfinity base/top boxes to sit flat and also gives better latch access. I did find myself shortening the model in Orcaslicer on the Y axis (length) from 44.66mm to 43mm (96.28%) for better cam-over feel. Screw install wasn't affected.

I don't have enough time to entertain any requests to modify this stuff. I'm not rich or skilled enough to hammer these out. I have included my f3d files for Autodesk Fusion so go on and to take my amateur work and make improvements. Let me know if I've made any printables-related mistakes though. First time doing this.
