Paint can plug remover

I recently purchased paint at a big box store and when I went to use it the device that was supplied would not work because they had put the plug back in too tight. I managed to find a work around that worked but damaged the plug. When I went back to purchase a different colour I noticed that they had a different tool for putting the plug back in. I asked if I could purchase one and they said that they did not sell them and had a hard time trying to get more. I went home and designed and printed my own. I included pictures of the original.
I have modified the part to fit the plug more easily. (stl version4)
