Ikea extendable table clamp

A tiny improvement over jipimac's perfectly adequate version.

This one works without the metal spring, I replaced its function with a tiny nook that works just as well to secure it in place when not in use, with the added benefit of a suportless print. I also strengthened the part a bit as we know it is prone to break.

Print upright with 4 or more walls/perimeters for maximum stability.

Kudos to jipimac for the original design.

Update: It seems the clamps from different generations of this IKEA mechanism are not exactly the same, as I found that there was a bit too much play with the dimensions I copied from jipimac's design. So I updated this with a slightly shorter version which now fits perfectly.
