3DR is a RepRap Delta printer. Designed by Richard Horne (Aka RichRap)

The design is highly inspired by the fantastic Rostock, Kossell and Tantillus 3D printers.

It's been performing well since May 2013 – but should be considered a work in progress.

The files here are provided for you to print, build, experiment and evolve the design how you choose, please share your experiences and modifications and do let me know if you build one.

Many people and projects have provided inspiration for this printer design. I would like to thank everyone working on RepRap projects the world over. Special thanks to -

Johann C. Rocholl for all the great work on Delta printers and firmware.

Sublime for the fantastic Tantillus printer using Spectra fishing line as the drive component and the various other great parts and designs used in the construction of this Printer.

I hope this work has been of some use to you, if you wish to say hello or donate towards further developments please see my Blog here - www.richrap.blogspot.com
