NO Stamp.

thingiverse

Had a gutful? Got the craps? Don't want to do that task? Then make good use of your very own NO stamp! As made famous by Pauline Pantsdown! Printing is simple. Prints nicely with PLA and at 0.2mm. Nothing fancy. Print the stamp head itself with the letters facing upward. You may wish to print the handle with a brim to better adhere to the platen. Once both parts are done, fill the handle hole in the stamp head with some super glue and place the handle in there. Give it a while to dry and you have a completed NO stamp!
