Potentiometer Mounting

I let the 3D printers work overnight and when I arrived this morning they were done. Because there is a large overhang, I used supports to make sure it didn’t collapse. The supports did turn out to be somewhat of a problem though, since they were attached to the small peg that slots into the pots. When I tried to remove the supports, the peg broke off along with them. For some reason the grey ones were especially prone to this, and I only got one grey one out of the 5 that I printed. Luckily all of the white ones survived.

I took off the old mounts and put on the new ones and now it looks something like this: I still need a way to attach the last joint to the last pot, and the first pot to the hand. The final plan is to have it be integrated into a glove, so maybe sewing it into the glove will work.

During class I thought of a way to attach the last pot to the end of the finger. It uses a ring which is attached to the potentiometer on the side, shown here:

I didn’t have enough time to print them out before the end of class today so I will have to wait until tomorrow to see if they will work. I could also make something similar to this for all of the pots, then they would be rigidly attached everywhere and there wouldn’t’ be a need for a glove.

Here are a few renders of what this might look like, once again I didn’t have enough time in class to print it. One problem with this design is that I would have to print it upside down compared to the old ones, but this shouldn’t be a big deal since the supports seem to come off easily, especially with the filament that I am using.
