Have you ever taken all those dividers out of your tackle box to fit bigger lures and then one day, you reorganize and want to use the box for smaller jigs but just can't remember where you placed all those dividers 10 years ago?

Well then, this fix is for you!

I designed this to fit in a 40x43 slot (it is slightly smaller to slide in nicely. Most tackle boxes have a slot width of around 3mm, so you will probably only have to resize the X and Y axis to fit your tackle box. The top edge is slanted to help it slide into the slot. I have included 2 files. The one I prefer is designed to print horizontally for strength, but to print it without supports, I had to add columns although some people may find aesthetically unappealing. Thus, I also added a file that does not have the columns if you wish to print it upright (which may be more prone to snap) or you can print it with supports.

I printed it in clear PETG.
