Magnetic Anti-Vibration Feet

thingiverse

I wanted to make some magnetic vibration pads for my turntable. There are others out there, this is my take (for now). At the current state, my Technics SL-D3 turntable sits on them perfectly with a bit over 1mm of air gap in these pads. I do know that after putting them in place, knocking on the table seems to pass less noise through to the speakers, so I think they at least do a little something. You need 6mmx3mm magnets for this design. Also, you have to be sure the two halves are put together so that the magnets are exactly on top of each other. IF you get the alignment wrong, the two pieces will suck together rather than repelling; it's freaky. Also, you'll need to be pretty careful about putting the two halves together unless you glue the magnets in because those little suckers will jump out and try to attach to a neighboring magnet at the first hint that you're not aligned right. I tested these on a scale and it looks like you can push down on them with nearly 4 lbs of force before they are completely compressed. I'm going to add more magnets and see where it gets me. I'm also going to try larger magnets because I want to try to put my tube amp on a set of these and that thing is heavy. The V2 files have more spots for magnets, so they should support more weight. I haven't tested them yet to see how much. I'm sure I'll be adding more variations as I experiment. Just added V3. it's taller and instead of several tiny magnets they hold larger disks. Each half holds two disks stacked on top of each other in order to get more force. The magnets I used for this version were these https://www.amazon.com/gp/product/B07PWP9DWC/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 One of the issues with the original versions is that they are difficult to keep stacked together as you're placing them under your equipment - actually kind of a pain. So the V3 has a little catch so you can push it together, give it a little turn and it stays together while you put it in place. AND, I added one more. The deep version of the V3 allows you to put 3 magnets in each half. Actually, you can put 4 magnets in the bottom with one sticking out just slightly. This version is holding about 10 lbs per foot. I have my 40 lb. tube amp sitting on 5 of them and it acts like it's on springs. Slap some stick-on cork sheet on them for padding and you're set.
