Fixed Bike GoPro/ActionCam Mount PETG Filament

The original design is a great idea, but the ball + threaded neck is too weak when printed in PETG. The threaded section snapped quite easily when tightening.
 

I noticed the original print profile uses ABS, which likely works better due to its higher rigidity. However, for PETG, some adjustments are needed.
 

Here’s what I changed to make it durable for PETG:
 

• Rotated the ball part 90° (printed on its side) so the layer lines run along the screw instead of across it  
• Increased wall loops to 5 for a much stronger outer structure  
• Made the part effectively solid (no hollow interior)  
• Used PETG at higher temperature (~250°C) with moderate cooling for better layer bonding  
• Enabled tree supports from build plate only  

I also slightly upscaled the ball to improve strength and grip in the socket.

After these changes, the part is significantly stronger and works reliably without snapping during tightening.
 

Overall: great design, but the ball joint needs reinforcement or different print settings when using PETG, especially for real-world use like bike mounting.
