Stellar job, that looks great! Although Dobby looks so terrified of you in that first full-body shot. 
It has an overall weigth of 18-19lbs.
Very cool build. I’ve been 3D printing for a few years now and it never ceases to amaze me the builds that can be achieved across the board with doing it. Great pack sir.
What adhesive or attachment method did you use to hold your PETG pieces together? I’m in the midst of printing my pack in PETG using Quentin Machiels MK2.1 designs (Thingiverse & the 3D Printed Ghostbusters Props Facebook group) and I haven’t settled on how to glue/attach the pieces together. I’ve seen everything from friction welding, welding, CA glue (super glue), epoxy, Weld-On (#3 or #4), etc. and I can’t decide.
Thanks!
WOW!!! Just WOW, I thought i had done atleast a half decent job of eliminating print lines but you nailed it… any advice as im also 3d printing my pack?
