A 3D printed screw clamp sounds like a completely impractical idea, so hats off to jakejake, who designed each part of this clamp (hsmag.cc/JPdFkL) with the grain of the print in mind to provide the necessary strength. Like the case below, we’ve printed it in 100 micron PLA.
It looks to us like a grown-up version of a toy, so would be ideal for any small engineers who need clamp you can trust won’t damage your surfaces.
