Desk Clamp for Articulating Desk Lamps (V2!)

thingiverse

I purchased an articulating desk lamp from a garage sale for just $2, but without a base. I needed a way to secure it on my desk in order to use it. Fortunately, this clamp is perfect for lamps with a 12-13mm base-shaft size and desks up to 4-5cm thickness. It comes with a nut trap designed for a 1/4"-20 nut, as well as a 1/4"-20 bolt or threaded rod. I used a cap-head bolt and a knob that I already had on hand. However, it's easy to print a knob for this clamp. The designer has since updated the files to V2, which includes a base that interlocks with the body of the clamp for increased stability. It also features knobs and pads for 1/4"-20 hex and cap-head bolts (a bolt between 1.5" and 2" is recommended). I printed V2 and attached photos to prove its effectiveness - it eliminated all wobble except that caused by the lamp itself, and the pieces fit together seamlessly with minimal trimming required. If you enjoy this design and find it useful, a tip would be appreciated. Enjoy your new secure desk lamp! Just remember to print at 20% infill (honeycomb) for sturdiness, but feel free to increase the density if you plan on being rough with it. The nut traps are tight-fitting, so you may need to heat them slightly with a lighter to insert the nuts properly.
