Seattle, WA
Quoted from PinRetail:I'm cheap so I'd probably cut a 2 by 4 wood block to set the back legs on to get more playfield pitch.
As it happens, I just uploaded the models for the leveler feet I made. They are intended to work with the foam & plastic furniture sliders you can get at the hardware store (Ace, Home Depot, whatever), fitting over the foam part and distributing the pin's weight better.
If you have a 3D printer, they are an easy way to get another 1" of height, on all legs or just a pair. I also have a version that adds only 1/4" of height, useful if you just want the benefit of spreading the load over the foam but don't need the extra height. Put the tall ones in the back, and the short ones in the front, to get the increased playfield pitch and the better weight distribution at all four legs at the same time.
People who don't own a 3D printer can still use them; often a local library will offer printing services, or you can send the file to an online service like Shapeways or Xometry. Some UPS stores have 3D printing services. Of course, the services charge money, but usually it's a minimal, reasonable fee.
