This was made for our Sub Zero 632-2 - it originally had icemaker part #4200521 which has been replaced with part #7002738, however the arm doesn't go up enough to shut off the icemaker when the bin is full.

This is a little arm extension I made that offsets the arm, pushing it up so that the icemaker will turn off. There's two STL files here - the 0.6" offset part works for me, but I've included the 1.1" offset part in case it's useful to someone (it was supposed to be 1.0", then 0.5", but I got one of the dimensions wrong - it worked, so...).

The pictures aren't great, but hopefully give an idea about how this extends the arm. It should be attached to the plastic arm (which goes in the recess) with a small stainless machine screw and nut. The pictures show a small nail instead - to be replaced soon.
