Active 3D glasses frame legs fix

Active 3d glasses - Non branded (Chinese - very similar to Samsung but legs connection differs).Found myself with 5 pairs of these glasses and they all break - mostly the connection where legs are slid into side of the glasses frame, and due to the arm being stretched to fit your head - I think its mainly down to the stress on the connection point. I also find the battery compartment tends to break (located in nose piece) so I've added in the back panel in a hope it helps keep the battery door shut.It may fir the Samsung type glasses too - as it appears that its only the connection of arm to body that differs (overall shape looks the same)Added some grooves in the sides (saw some similar on here somewhere) just to allow for some movements.Print it up side down (end of legs going up into the air)
