This is sized to work well with a Tonka 952 crane. I'm sure it can work with other things too. Scaling should work, however the alignment pins might require some adjustment. Truthfully, the alignment pins are probably not necessary at all. I made this with OpenSCAD. Let me know if you want the source code posted up here.
I removed the original scoop attachment and tied on a lanyard hook so it can be easily changed between scoop and wrecking ball.
I printed in esun PLA plus on a 0.4mm nozzle at 0.10mm layer height. Three perimeters, 5% rectilinear infill.
