Here are the notes from Beat Saber. I printed this on the Ender 3 and it required a little bit of sanding to fit. Be sure to print with a smaller than .2 mm size, as it wont fit otherwise. Another tip, (since this is my first model) try to print the arrow scaled just a little bit smaller so the clearances are right and it will fit. The block wont need supports if you have the arrow side facing up when printing.
