The thread of the PETG Carbon Fiber Prusament Clamp can now be printed horizontally for improved strength, reduced print time and slightly less material use.
PLA is totally fine for this.
I used Recycling Fabrik rPLA for the entire clamp, but for the round jaw I went with PETG.
The author remixed this model.
I removed 5mm from two opposing sides of the thread to allow easy horizontal printing for improved strength, reduced print time and less material use.
