Yes, you can control the size of each item when you convert the stl to a sliced x3g file for printing. You can print at 100% of the original and if that is to large then you can start choosing smaller versions of the file to slice and print.

Thanks for telling me. Does anyone know of a place that can 3D print near the wyoming area, or can someone print these for me? I may not be getting a 3D printer, it's a pricey investment.

Also, I'm going to use up all 24 digital servo ports. Could I use 2 analog servos to open/close the hands?

The original designer of the hand I posted info about used rubber bands between each (knuckle) to hold the hand open and then connected fishing line to each finger to pull the hand closed. It may be possible to connect a single servo to turn and pull all the fishing lines at once. Torque would be an issue as well as how strong the rubber bands are that hold the hand (fingers) open.

What i'm going to do is what the melissa hand does- it opens/closes using a single servo. I'm going to add two hands, so I was wondering if I could use a analog servo for each hand. Thanks!
