i found the original file http://www.thingiverse.com/thing:645914 on thingiverse.
I remixed some parts.
The fingers can make ad- & abduction movement.
The wrist can flex know. And with the spring loaded pistons it will return in its original position.
The hand pistons are not spring loaded. These rods are made from 2mm aluminium rods
I made a new elbow piece, the arm can now pro and suprinate. If you already printed the "old" version. I have included an adapter piece for the elbow connector.
The upper arm and elbow are movable in flexion an extension. The upper arm will be fitted with a shoulder part.
This is NOT a full replica. Just an attempt for me to get acquainted with 3d printing and modeling.
This is still a work in progress.
Using repetiere and slicer, gives no problems. It will slice the parts even if they are not manifold. However other slicers may find the parts difficult to slice. If you encounter such a problem, please contact me. so i can try to adjust the files.
uploaded more files including sketch up
I uploaded the missing parts. The shoulder top part and the upper arm cover stl.
The most parts are printable without support.
The finger tips where printed with support.
The "old" elbow needs support.
The 3 small pistons, can/must be fitted with springs. So they can be pushed in, and will return to its position.
Take the outer part.
Insert a spring.
Place the piston part in the outer part.
Place another spring on the piston.
Slide the piston cap on top, to close the outer part. If nessesary, you can shorten the inner piston part. I glued this cap.
Then glue the 2 parts on top of the pistonrod. Use the balplate for calibration of the right depth. When they are to deep and the bal can't move. you can use a washer to gain the right depth. To shallow an d you don't have material left to be bent around the connection balls of the handplat
The large piston, will be to tall. I left it this size, because the length is depending on the springs used for the small pistons.
I had to cut off a small section. Then glue the top, to the piston.
The piston ends will fitt snug to the piston balls (handpart). To make them hold on. I heated the top of the piston ends and bend these to the inside. So they follow the contoure off the pistonballs.
The second handpart is glued on top off the part with the balls.
The upper arm can be bolted together. Before you place the upper arm connector rod. Place the shoulder connector first.
I have uploaded the anterior piston, the alignment is not 100%. I am trying to fix this. This gives no problems at building. But the inner piston will hit grind the piston cap a little bit.
Shoulder part 1a fits in shoulder connector. Make sure the bold witch connects the shoulder connector is NOT to long. Otherwise the shoulder part 1a will not move. Push shoulder part 1b through the gap of the combined shoulder parts. When this part is placed. And rotates fine, glue the endcap (shoulderpart c 2x) on each side..
