I printed these in PLA at 20% infill at 0.2 layer height. You will have to use screws to attach the legs to the base of the tripod and a screw so that the clip can hold correctly.
You may have to scale the model up as I had to after exporting the files. The following is what I scaled it to.
Base Tripod=Scale the Z axis to 12.7 mm and turn Uniform Scaling on
Tripod Leg=Scale the X axis to 200 mm and turn Uniform Scaling on
Clip=Scale the Z axis to 12.7 mm and turn Uniform Scaling on
