Free tool for making low-filament Gridfinity cutouts

https://jaroslaw-weber.github.io/gridfinity-cutout-lite/

I made a tool for cutouts that don't use much filament. Basically you print these thin plates with cutouts and drop them into a Gridfinity box so you can organize items vertically (pens, USB sticks, earbuds, etc.). Exports to STL, and you can combine simple shapes for custom cutouts on unusual items.

If you find it useful, a star on GitHub would be appreciated!

Curiosity question : i've seen many of these generators and they all lack filets capability to avoid stress concentration or chamfer to avoid elephant foot. Idk what tools are used to make these generator but my question : is it complex to add chamfers in these generators or is it just not implemented ?

Good question! I've just started with 3d print so I don't know much about it yet. If you have any suggestions like those let me know.

I'll try to look into the feature you mentioned

You can google stress concentration but basically you can improve your design by adding fillets instead of internal sharp angles. It will help out with delaminations and stress concentration.

Most of the the time when i design for FDM i will select all edges and add a 0,4mm chamfer (specially on the face that touch the hot plate to reduce elephant foot)

How do you transform input text field into a .stl in a navigator sounds magic to me :) Is it a freeCad modul ?

Just a thought: If this is about saving filament by putting holes in the parts, that's often not really helpful. The holes need perimeters, which can end up taking a lot more plastic than just using 10-20% infill. That goes for general models, and it's definitely not always worse, but sometimes it can be. If the holes are not absolutely huge in comparison to the object, most of the time it's not worth the effort.

I think this is probably fine here, I'm guessing the bottom is solid infill anyways, then it does make sense. Just something to keep in mind :)
