Hydraulic Arm

(I didn't test this so it can fail or not work)
This is my first 3d project.
This hydraulic arm is based on italian syringes (i think they are universal), since i am a newbie i used some pieces from other peaple's project (the arms and some other little pieces https://www.thingiverse.com/thing:1328020 ).
hope you enjoy it :)
EDIT (4/8/2017)
⋅modified the base to make it easyer to print with supports.
⋅the mid piece wasn't touching on the bed (i don't know why) fixed.
⋅modified a piece to make it bigger
EDIT (16/8/2017) do not print the model, it needs some tweaks
