Dr Potato Head w/part backer
thingiverse
I made the [original](https://www.thingiverse.com/thing:560765) and had issues with the holes being too big and made some backers to hold the pieces in place. The goal is to size them so that they fit with the part snug to the "potato", where the taper of the part post is the widest. One side of the backer is beveled and the other is flat. I find the fit is best with the beveled side against the potato, but feel free to do what works best for you. Happy printing.
