I have a Luxo lamp. It has no clamp.
My desk is abound with clutterous mounds,
So to clear that pollution, I wrote a solution.
Not knowing openSCAD, a solution I had,
to make something new from primatives, true.
But emergent from these, some complexities.
So now we will see, if bullshit I breath,
or something half decent, I'll accomplish most recent.
For god knows I can't write a poem.
Run openSCAD, change the variables to fit your desk. Most of the luxo lamps have a mounting rod of 60mm diameter, but ya. Play around.
After printing, you should pad the bottom of the upper clamp, and the top of the screw used to brace the object.
After that, enjoy and please share any varients.
