Hydraulic Piston (simple Syringe type)
thingiverse
This hydraulic piston platform was initially planned for simple linear mechanical energy transference with 3D printed adaptability. However, issues arose, including a non-watertight outer cylinder, which was fixed using ABS dissolved in acetone. Leaks also occurred around the plunger's O-rings, resolved by dipping into ABS/acetone solution. Despite these fixes, leakage persisted at the O-ring's edge, indicating possible ridges as the cause. For improved performance, I suggest using actual plastic syringes, with printed plungers and a holder for the syringe cylinder. For larger pistons, PVC tube might suffice as an outer cylinder, due to its smoothness.
