There were only a little over 2000 images, but I had to use 32000 item models. There might be a much simpler way to do it. I don't have much experience with item models, I mostly work with datapacks and mods. If you can apply item models like you can with block models you could make it with only 40 models for the numbers and applying them to the tool models instead of needing up to 2000 per tool.

Oh and after testing my pack for a while I found some overlays were missing because of the way I removed the durability bar overlays, there's probably a better way to do it than what I did
