The parts were printed mostly in white and red PLA. C-clamp was modified to flexible material on contact surfaces. Infill was set to 40%. Unfortunately arms are therefore quiet flexible so I would recommend higher infill.
The c-clamp body and cap were customized and they were printed in white PLA and grey TPU with multi-material extrusion.
Filaments used: red and white PLA (Voltivo) and grey TPU (NinjaFlex)
