This fully printable C-clamp has been designed so that the screw portion prints flat on the print bed, which allows the layer lines to be optimally oriented to create an impressively strong functional clamp.
Five different sizes are provided with clamp opening sizes ranging from 3 cm to 10 cm (and the “mini” version has a bit of a cute factor). The threaded hole is designed with a keyed knockout, and so no supports are needed to print any of the parts.
The author marked this model as their own original creation.
