My HVY and HWZ fit together fine without glue, and the INF are made to snap into the bases securely (the 1 I assembled easily stayed together when I accidentally stepped on it, though the INF did get smushed )-: ). My Mk III, OTOH, is 100% glued (super glue - a tiny drop is all it takes), and I expect the Mk V to be the same way, along with the GEVs and probably the CP. Not sure about the MSL yet...
