An amazing user of our super amazing 3Dprinter 3Drag (See it here http://www.open-electronics.org/3drag-3d-printer/) put togheter all the 3dprintable parts on a Thingiverse set! See > K8200/3Drag printer by xmosh – Thingiverse. (Note that K8200 is the alternatie name of 3Drag as distributed by Velleman).
Be noticed that this is still a work in progress.
