The Top 40 websites to download Free 3D printer files Pinshape For here, we intend to provide you with a list of 40 online platforms where you can find free STL files for 3D printing. Therefore, if you are one of those who understand the power of ‘free stuffs’ then you are at the right place. Progressing further into your learning process, you would also come to realize the three ways-computer aided design modelling, using a 3D scanner and accessing free 3D STL files-in which you can get STL models to feed your 3D printer with.Ī quick perusal of these three processes will show that the effort to be put in with CAD modelling or getting the money to purchase a 3D scanner is quite more than simply finding different sources to access these files freely.
