Yamaha DTX Phone Holder

I downloaded, and printed the original files. When I went to put it together I destroyed the pipe clamp, and the big nut. I thought maybe my threads didn't print well. I eventually figured out that the big nut had left handed threads, and the pipe clamp has right handed threads. I also added a version of the pipe clamp without the Viking head on the sides & made a bigger version of the phone clamping pieces to fit thicker phones or phones with cases. I printed this in PETG with .20mm resolution & 100% infill. I used SUNLU black PETG, and the textured steel sheet. I had to file the Phone clamp little bit because it was such a tight fit on the phone arm. I am no expert in CAD so I don't know how to fix that. I also used the pipe clamp & the big nut to finish screwing the ball into the phone arm. You really need to take your time and start the threads slow to make sure you get them straight. I made this model better not perfect.
