Hi Cliff, I would probably start by printing out (on paper) the outline of the top view of the hand at 1:1 scale. Draw on the paper the dimensions you think you want to achieve and calculate the reduction ratio (the length you want divided by the original length). Then you could scale the palm/fingers/top cover by this ratio in blender but leave the motors/pcb/pcb holder at the original scale - they will probably pop through the sides of the model. Print out the scaled model on paper and verify that it looks right. Then see if the pcb assembly can fit at all (there is some plastic that can be trimmed off one side of the pcb holder, but maybe not enough), if it doesn't you will need to take the pcb external and use a daughter board to connect the motors to the board via ribbon cable or similar- make sure the cable you use can support the max current the motors will draw and also that the cable length does not impede the signalling. You will need to find space in the hand for this daughter board. Also check that the thumb motor will fit, if it doesn't you may need to find an alternative motor. Then you can start removing finger motors and rearranging them. I would start by trying to align the actuator arm to point down the centre line between the fingers it is intended to actuate, though there may be a good reason to align one of the motors directly on the index finger, you may need to experiment here. You would then need to make sure the cable channeling lines up, print, test and iterate. Good luck jd.
