I really had a hard time to build my Seismus, @fakebusker83
. Print was in WSF as tested by you. Yet almost all balljoints popped out of their sockets (especially the hip joint still does now and then) or they didn't fit until I had widened the sockets a little. It is still a fragile piece, so I doubt it would survive one transformation into weapon mode without falling apart completely. What a pity.
