A replacement set on non slip knee joints for Transformers Generations Metroplex.
Metroplexes knees are pretty flimsy on the original figure and the forward bend can cause all sorts of problems.
(Falling and crushing other figures was mines speciality)
These knees no longer allow Metro's legs to bend forwards and still allow a full 90 degree back bend.
I've added an extra spindle to the centre of the joint to allow easier connection and to give a little more flexibilty in city mode.
If you wish, I've added room for a 2mm pin through the joint for even more added stabilty and to keep the peg firmly in place.
This model should also fit the upcoming Titan Wars Fortress Maximus figure, Let me know if it needs any adjustments for it of you can guys.
