Instructions for build the Galileo Hand - Thingiverse
Instructions for build the Galileo Hand The fingers We are using the fingers of the Cyborg Beast, you can download the .stl files here http://www.thingiverse.com/thing:261462 there is a lot of instructions that you can use to make the fingers work. Materials Chicago screws www.chicagoscrews.com Aluminum Chicago Screws – 3’’ to 3 1/4"(or larger) for the knuckle. Size will depend on the width of the hand. You need 1 per hand. Stainless Steel Chicago Screws 1/2’’ for the fingers. You need five 1/2 ‘’ for the fingers. you can buy these parts in your hardware store. Shade Cord (Or Lift Cord) 0.9 mm (http://www.amazon.com/RollYardsShadeCordLift/dp/B006DDHVM8 ). It is sold by a roll of 100 yards, but you need about 2 yards. 2mm Black Elastic Bead Cord (http://shop.hobbylobby.com/products/2mmblackelasticbeadcord183418/ ). It is sold by a roll of 5 yards, but you need only 1 yard. The shade cord and the elastic bead cord is used for making manual stuff like Crafts, or Jewelry. For printing the fingers when you print this files you have to adjust the scale of the parts to 150% print the file “Finger_CyborgBeast6.4_original.stl “ 4 times print the file “Proximal_Phalange_Cyborg_Beast_7.0.stl” 4 times print the file “Thumb_Cyborg_Beast_7.0.stl” 1 time print the file “Thumb_Prox_Phalange_Cyborg_Beast_7.0.stl” 1 time
The hand
for printing the palm.stl file it’s important place the palm as show in the following picture, you can use supports and rafts, this part doesn’t need to be rescaled.
When you put the elastic cable has to end like this
for the test you have to close the fingers and they have to come back to his open position, the elastic cable has to be tense.
the finished assembly should look like this.
Cover
for printing the cover.stl file it’s important place the cover as shown in the following picture, you can use supports and rafts, this part doesn’t need to be rescaled.
The thumb the thumb.stl file is ready to print so no problem for the position that you print, it has 2 holes the red hole is for the cord that closes the thumb. the blue hole is for the Elastic Bead Cord
the other part of the thumb is the blocking mechanism the red part is the end of the Elastic Bead Cord where you can make the knot
in the picture we show how the blocking mechanism is assembled, this has 2 parts the first is the spring (pen spring) and the second is a rivet, it has a diameter of 2 mm and works like a trigger, we actually cut the rivet to the appropriate size.
and tornillo.stl file is the screw that joins the palm with the thumb part, it has to rotate.
5 to 1 mechanism the 5to1.stl it’s the part that joins the 5 five Shade Cord of the fingers and convert to 1 cable that is activated with the shoulder
We use beads to calibrate the movement of the five finger and after that we use super glue to hold it in place. the idea is the all the fingers move at the same time, the thumb has to move but not much. you have to place this part in this way.
