Sinclair C5 Reproductions/Parts - 3D Printing

Here is a collection of Sinclair C5 parts I have reproduced using a 3D printer. Some of them original parts, some of them new parts. Follow my 3D Design and Print blog for C5 and other 3D Printing projects.

We are the first website to create 3D printed parts for the Sinclair C5.

If you are interested in 3D printing we can recommend to convert your OBJ, 3DS, VRML and X3D model files into STL files suitable for 3D printing and to create 3D STL models from PNG or JPG image files.
