Articulated Line Prop for Artificial Grass, the tolerances are quite at the joint, square hole for line prop 18.5m.
Ensure you use a high infill, I make the stressed areas at 100%. which is basically the whole centre of the base and the bottom half of the top piece.
If you need to change the sizes, the model can be found in Onshape, search for “Line Prop Foot”.
The author marked this model as their own original creation.
