I’ve had many requests to offer a shoe last for purchase (sorry we don’t have this ready yet). So, while we are working on a way to cost effectively supply you lasts and outsoles, we have put together a .STL 3D printing file of a great shoe last for you to download.
This last is great for your DIY shoe projects. This last has a standard athletic 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 last has a toe spring of 8mm. The feather edge is in the middle between sharp and round so you an make a stobel pattern or board last without difficulty.
The file is 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.
