> This is the first part of a video tutorial series that teaches how to use Segment editor. This tutorial explains how to create a 3D-printable lumbar spine segment that can be used for lumbar puncture training: The video tutorial was created by Hilary Lia (PerkLab, Queen’s University), with help from @cpinter, @lassoan, @ungi. Please post your comments here about how useful this tutorial format is, what did you like/what to improve, what topics/techniques/anatomical structures you would be int…

The Smoothing effect in Segment Editor (see at 5:00 in video) can make your model more suitable for 3D printing.
