This is an accessory base cap for Desk Lamp from @aceofsuedes and @ggoss so the stem of the lamp won't scratch the desktop. I've also added the screw that's split in half for easy printing (print w/o support, superglue them together).

Original STL files copied from for the clamp and base are from @aceofsuedes: https://www.thingiverse.com/thing:2651207. Please give the originals the likes!
