Gridfinity Layout Tool — plan your layouts before you print

So I got really into Gridfinity a while back and kept running into the same problem: I'd measure a layout, do some napkin math, start printing bins... and then realize my layout didn't actually work. Wrong sizes, forgot about that one bulky item, or just didn't like how it looked once I started placing things. 

I ended up building a little web tool to plan layouts visually before printing:

You set your drawer size, click and drag to place bins, and can see a 3D preview of the whole thing. Nothing fancy, but it's saved me from wasting filament a few times now. 

Some things it does: 

• Drag to draw bins, resize them, move them around 
• Multiple layers for deeper drawers 
• 3D preview so you can see how it'll look 
• Generates a print list with rough filament estimates 
• Works on your phone too 
• No login or anything. Just saves to your browser 

It's free, no account needed. Feedback welcome if you try it out and think something's missing.
