I can't remember where I posted it before, or I'd link to it... heh. Normally if it's riding low I pull the platform and re-seat it, but it's not really easy to do without damaging the platform or the rod or both. So what I did last time is I removed the magnet from the lid, carefully removed the plastic pieces, etc until all I had was the magnet. Then I took the side off a computer case, set it on the desk, set a sticky address label (avery brand, but any sticker would do really) on the computer case, then set the magnet on top of that. The magnet stuck to the side of the computer case and held the address label in place well enough for me to trace the magnet onto the sticker. Once I'd traced the magnet onto the sticker, I removed the magnet and I took a hobby knife and cut out the doughnut shape... this ended up being a perfect sized spacer to just stick on the platform. I made two of these... stuck them on the platform, and they worked great. ;-)
