On Easterhegg I had an idea of how to further improve the rigidity of my 3d printed shoulder rig.
If, like me, you choose the path of using a Seagull as a glorified shoulder-pad,
then a specialized set of MiddlePiece -variations can replace the 3 default MiddlePieces below the camera-plate.
These are designed to clamp the part of the Seagull that has the mounting-hole and thus restrict any possible warping of the 15mm rods due to less-then-infinite clamping-force and the high counter-weight trying to shift.
