Use this link to access a 27 minute video on 3D geometry.  I would NOT recommend having students watch ALL of this at once but rather use parts of it as is relevant to your units.

I am a teacher and I use educreations a LOT to create video notes for my classroom.  This video is intended for my honors 6th grade students (preparing for Algebra I in 7th grade) but you could use whatever parts are relevant for your curriculum.  You could also create a "fill in the blank" notes if your students need that level of scaffolding.  I'll post some videos and scaffolded notes that went along with it that I use for my standard level students (studying only 6th grade material).
