Design Goals
The following list summarise what the ScrewRap hopes to achieve:
- Minimal tools. I want assembly to be as easy as possible. The tools I'm thinking of are allen keys, screwdrivers and maybe a drill. This list may increase as time goes on, but not by much.
- Cheap. Even though I'm using leadscrews, I still want the rest of the printer to be as cheap as possible.
- Accurate. To achieve this the design requires a sturdy frame and precise linear motion components.
- Easy to source. I want to avoid custom made parts as much as possible, and use standard parts such as T-Slot, Stepper motors, Bearings etc. Where speialised components are required they will be 3D printed. The leadscrews may be slightly more difficult in sourcing than the rest.

Inspiration
The following list contains all the sources I've found inspiration or parts for this design
- smartroad's Dual-Struder Fabricator. This is the foundation for my design, with everything else being built on top
- Jspark's Kid Mendel has the option to use leadscrews for all axes. He's also used threadless ballscrews which I may investigate in the future as a cheaper alternative.
