Snap Together Hydraulic Cherry Picker

Create your own model or use a kit to build a wooden structure. I love playing with it, and with my Replicator, I thought of reproducing it in ABS plastic! The pins will fit perfectly, and there's plenty of space left if you want to add more features. However, there are some non-plastic items needed for operation. Have fun! To reproduce: print the 7 required STL files which include the skp files. Assemble it as shown in the picture - it's simple and easy to figure out! For operation, you'll need two plastic syringes (available at drug stores or kitchen supply) and about 16 cm of tubing that fits over the nozzles. The syringe plungers should have a hole or loop for attaching wire. Attach an empty syringe to the eye screw in the bottom support arm using wire. Place its nozzle into the other eye screw, and attach the tubing filled with water (food coloring optional) to the other syringe's nozzle. Pull back on the plunger to suck the water, tap to remove air bubbles, and push the water out until there are no more bubbles. Attach the tube to the nozzle in the eye screw and push the plunger on the free syringe. Watch as the arm goes up and down! Don't forget to add pins for the structure, and feel free to design your own basket or platform for the strong arm to pick up items. Stay tuned for updates on a hydraulic lifter replacement for the syringe attached to the arm! Enjoy creating and experimenting with your hydraulic system!
