This is my first Diy battery rack. Any advice on how to improve it or important things i may have missed?

Yes those steel plates look 1/8" thick. They will be too elastic at that length and will not be able to spread 11 PSI compression force evenly across entire cell side. Leaving it the way it is now is fine as long as you don't care about corner cells which will act as force spreaders to remaining 14 cells in a stack but will not be optimally compressed themselves. This assumes those 4 springs are at 50 Kgf each for 200 Kgf total. I doubt it. So it looks like entire compression apparatus is not applying enough compression to be effective.

The yellow steel plates are 5mm thick, the springs are holding 75kgf each.
I checked for bends on the plates and they have not bent at all.
It seems to be rigid enough but i will continue to check from time to time.

it's clearly been designed with significant thought, would you be willing to share the 3d print files?

Sure. If the admins allow for file sharing i can share it no problem. I dont know if there is any rule about it.
I also can cad any bracket, holder, spacer, connector or weird part that doesnt exist in 5 minutes if anybody needs it, i do it all the time.

Doing more research, mosty harmless
There is no rule against sharing STL files. Treated no different than any other file type. Now if it is a multi-gig affair that might be different

There you go, i have attached the stl file of the template

I think there should be a section in the forum for file sharing, manuals, sketches, stl and cad files, etc, you know?There is no rule against sharing STL files. Treated no different than any other file type. Now if it is a multi-gig affair that might be different
Pool together more resources for everybody to use

They should be in a holder. The fuse is not structural, and the wire will be free to short out power from the other batteries.
Just my preference: on the bms busbar connection, I would put the 2 bms wires on the outside, and the single wire in the middle. Current then flows on each side of the connection for the single wire.

There already is a Resources area in the forum- https://diysolarforum.com/resources/

Yes i have been concerned by this. I will probably diy a holder connected directly to the main busbar, or even better just to 3d print a bracket that will clamp the positive and negative wires before the dcbreaker connection.

Oh i see. I am not sure in what category stl and cad files should belong though. Beginner's resources?
Having a tough time trying to figure what to name this section. What do you guys think

If I can do it, you can do it.

DIY plans and files?
Resource section added. Labeled it as DIY plans and 3D printer files for now
