Thanks, I found an easier way to hold the drill bit in place. Just get a cup, cut it in half, then tape it together. Next use the drill bit to drill a hole in the center using the concave side. Tape the outside edges for support and boom. Drill Guide.
The crack in the glass is on the inside, I kinda put too much pressure on it and it cracked through. I was kinda inpatient lol, I literally just made this after I read your comment, and was eager to test it out.
