2017-oct-19 : revision 6, with ribs to reinforce the small sections on the sides, without that they tend to move in closed chamber printers

The original plateform jack was quite a challenge to print :)

Now we printed a lot of them, and in the meantime I've optimised some details to make it easier to print (angle at the top of the screw, contact at the base, bridges, ribs) and added an embossing with the OpenEdge logo making it a nice giveaway. There is also a blank version to edit to your liking.
