The original model wasn't working for me, the head hole simply wasn't big enough to fit, maybe because my printer is cheap and I didn't adjust it to nanometers sufficiently, so I simply enlarged the head. If you're lazy like me and just want things to fit, maybe this is for you. Print on PETG, no fancy configurations. Each piece weighs about 1g, and a pack of 20 takes about 3 hours to print. Put it to print and go to sleep.
The author remixed this model.
The head is larger for more comfortable use. And you, do you like a large head?
