> 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.
