My wife wanted a witch nose for halloween. I went here on Thingiverse, just to discover there was none to be found, so I used what ever little talent I have, and made her one ;)
I printed it in Fillamentum TPU Flexfill 98A. This gives it a bit of flex, but not to much. Can also be printed in PLA, or even in softer TPU.
For my 4 year old kid I scaled it to 75% and it fits him perfect.
