three jaw chuck v2.0

thingiverse

I didn't know... ... if someone has already print my original version and since the spiral block is the only part that is re-used, I decided to make it a V 2.0 now.. Concerning to my original version, the spiral got deeper as well as the teeth of the claws. I also made the claws longer so that they won't jam if you push them together. Therefore, I enlarged the side holes of the turntable, so the claws can run out of it. This makes the gripping area much wider. They're also flatened so you don't need supports print settings are like the old version but maybe you want to play around with them. Sadly, I forgot to take a picture of the new version.. this will follow Post-Printing How to build it All you need is a bunch of M4 screws and maybe a M4 nut. The axis is a M4x60 screw. I took one with conic head since they are smaller than lense heads or cylindric ones. Push it through the turn table and then put the claws in. try to push them as close to the center as possible. Next, put the spiral block on the screw and turn it until it engages with the claws teeth. Fix it with a nut and try to turn it. If the claws don't close evenly, try to exchange two of them. Then fix the spiral block with three m4 screws on the axis. Last step is to put some screws into the holes of the turntable to fix the claws positions when holding a coil corpus.
