Mr. Fisher - Drywall Insert

This is the v3 of my beloved Mr. Fisher.

I tested them on drywall and they work pretty well, like normal one.

Please print with the lowest layer height you can and with high temp to increase z strength.

*Please be sure to give them a couple of test to tune your print settings, if print temp is low they will be weak and so therefore dangerous.

......v4 is here with a better philiphs grip on the tip and internal faces of the hole now have a slightly inclination!
