This is a miniature "Iron Weight". Suitable for setting a trap to crush The Roadrunner, that can't possibly go wrong, with hilarious consequences. I've included the OpenSCAD so that you can scale it down, or just scale it down in the slicer. I used 20% infill, because it will take forever to print it solid. I used blue glow in the dark filament, and scaled it down to use it as a string pull for a light fixture where you pull a string to turn the light on and off. The glow in the dark "5,000lb. Weight" makes it easier to find in the dark, and every time I turn on the light, it recharges the glow.
