this is a scooper I made to go onto a mason jar. You just need a jar and a threaded band. Insert the print as if it was the can lid and you are ready to scoop goods into your jars.
I printed mine with 3 walls. I wanted to make sure the scoop had ony walls but the base was made up with bottom/top layers mostly. I did not want the base to have concentric stress lines as I thought that would be a weak spot.
The author marked this model as their own original creation.
