This is just a little joke between me and my friends. I just finished designing this model today and thought it would be interesting to share it here as my first work. I even deliberately added a few holes on the back to make it easier to insert safety pins—after all, that's how I use it myself.
Also, sorry for the poor image quality. I was in a hurry to finish it at that time. Well, that's it. But the printing effect is really great! I used PLA+ material.
