do you have an old IBM 5151, 5153, or 5154 monitor with crumbling rubber feet? here's a replacement option for you. 🧵
get a sheet of 3M SJ5009 feet which are pretty close in shape, size, and color. however you will need to modify them a bit.
first, punch or drill a hole for the mounting screw. it's around 3mm.
you'll also need to make a counterbored hole about 3mm down and about 8mm diameter. I found a rotary tool that was just the right size, and I used their routing attachment to control the depth.
the counterbore turned out super clean but it doesn't have to be perfect. next, use a knife or side cutters to trim the lip off the edge of the bumper.
the original rubber foot has a metal washer molded into it. I found a #6 washer, about 9.5mm, fits pretty well in the new one.
be careful so you don't overtighten the screw and strip the plastic boss. the result looks pretty close to the original, doesn't it? hope someone finds this useful.
