This is an apparatus for locking 10ml syringe in vacuum during a fine needly biopsy. I designed this for a radiologist friend. I'll post the feedback on this piece when i get it. I made this one on my RepRapPro tricolor, so printing it as two separate parts and superglueing it was the better option. I included the single part version as well, incase your printer can print it like that. See the video for the usage. Update: Turns out the apparatus was quite handy. He used it in more than 10 biopsies already. My choice was to print this as two parts, then join the 2 flat faces with superglue. Just see the single body part for alignment. Align the bottoms of the pieces, there should be a gap for syringe handle in the middle. http://youtu.be/SXrFJkoLMrc
