Added a derivation to the hinges in Grab Toy ++ (https://www.thingiverse.com/thing:2750749) so that I could have sets of parallel expansion frames and do things like this terrifying beauty here!
The default slack of 0.5mm for the hinges is a good starting point. If in doubt print the HingeSlackTest() model from Grab Toy ++ before, to see how small you can set the spacing between the moving parts.
HingesOfDeath(): renders the thing.
TheTwinHingesOfDeath_slack05.stl: the thing rendered using 0.5mm spacing for the hinge cores.
Enjoy!
