Index to 3D Printer Modifications and Prints.

You can find out how I drifted into 3D printing on this page.

Some of the things which I have printed, I have designed myself but the majority of the prints which I make are from designs in a huge repository of 3D printed models,

available freely on a website called Thingyverse. There are other sites offering designs free of charge, including NAS, and some sites require a small fee for a design.

The vast majority of the designs can be printed free of charge but can not be sold for profit as they are  licensed under the Creative Commons - Attribution - Non-Commercial license.
