The other dummy 13 posable hands and fingers didn't work well at 200 percent scale, the fingers were too spaced out, and you couldn't reliably print them with a .4mm nozzle. I used an older model as a guide but I designed these fingers from the ground up to be printed for a 200 percent dummy 13 with .1 layer heights and a .4mm nozzle. They even work with PLA but preferably PETG. They snap together really strongly and don't pull off unless you REALLY try.
In one of the pictures I'm holding a single finger tip with pliers and an added a .5kg spool of filament for weight, I could have added more! I spent months redesigning these and making them over and over again to be strong, keep friction, and have a good range of movement.
To make the right hand palm, use your slicer to mirror the left hand. I had the best results when I print the palms one by one, but if you can get away with both at once, more power to you!
When assembling go really slowly when pushing the fingers onto the palm balls with firm pressure and it helps if they're warm. Once they are on they shouldn't go anywhere. They hold things well and are easily poseable to give some extra personality to your robot. They have good friction and shouldn't get loose.
The author remixed this model.
remixed for the dummy 13 and resized to 200 percent instead of 500 percent
