3D Print File for Shoe Last
You can make your own shoe last! This last is great for your DIY sneaker projects. The last has a standard outline with a well curved arch, plenty of toe space and is relatively thick on the lateral side so its fit is accommodating. Heel lift is 6mm and the toe spring is 8mm.
The file is for a men’s size 9 last. You can make your own size with a little creativity. The .STL file can be scaled in X, Y and Z. While a technically perfect last grade is not made by direct scaling, this size 9 can be graded into a 8 or 10 without getting too far off the standards for last making.
If you have access to a decent sized 3D printer you can print this last full size in about 5 hours. We have a really slick MakerBot Model Z18 on hand so we tested the file.
We printed the sneaker last with 0% fill, 2 shells, and scaled to 275MM long USA size 9. With 0% fill the last is fragile but perfect for filling with expandable foam, casting resin, or plaster for a more durable last.
