Gridfinity-SP (Snap-in-place, Print-optimized)
Sooo, I recently started printing some bins for organization of my toolboxes but haven't yet started on baseplates. And I was trying to develop screwdrivers kinda-universal storage when I realized I probably need units attached to baseplate. Magnets? No way, I have over 36 drawers with various tools and I need more. Plus I will need to attach baseplate to a drawer and mine are wooden.
Ultimately, I tried clickbase / clickfinity. With my default settings the effect was quite phenomenal, more like a spider web. Of course I had particularly stringy PETG loaded at the time but still. And I recently saw this post.
I ended up modifying Gridfinity plugin for FreeCAD to print these click spring with much less retractions. Adding screw holes in the junctions was easy after that. And then I though that edge junctions are free and I could connect bases with clips there... So I added clip cutouts and later added clip generation.
Clips turned out to be tiny for the force they required. No way to install them without nose pliers. So I designed a tool for installing them that would hold a couple of them and align baseplates and clip to the right place. I think it does make connecting them easier.
I think next step is to make bases stackable for multi material print.
