Cattle ear tags

I first started 3d printing 5 years ago when cattle ear tags were starting to get more expensive and when covid hit I couldn't find enough in sequential order for our needs. Printing our own saved us money and allowed us to make custom tags. These take a common Y-Tex button or I've added my own version that the main body is printed in tpu and the piercer made of your own choice of hard plastic. pla doesnt work well when it gets hot out. Tags need to be printed in 95a tpu. unfortunately ams tpu doesn't work 25 percent infill
