Monoprice Monolith M560 Magnetic Earpad Plate

thingiverse

Like many owners, I discovered that the stock earpads on my first generation Monolith/Monoprice M560 headphones were just too small for my liking. I designed a 3D-printable plate to allow me to swap out the generic (10cm, round) aftermarket earpads without having to sacrifice the original pads and their mounting plates. Each plate requires four 9mm*2mm round neodymium magnets, which make it easy to attach or detach the pads as needed. The pins in the plate also ensure that the pad is properly aligned with the cups. I've included a Sketchup file so you can modify the design to suit your earcup size or preferred magnet type. You could probably fit larger pads by increasing the outer diameter of the plate.
