Even though I don't own one, I recently had a MM owner asked me to design some custom flipper toppers based upon experience with my other mods. As a result, I thought I would offer them to the group. The toppers are 3D printed at high resolution using high quality filament. The background is textured with a colored handle and blade on top. All colors are customizable by the purchaser based upon the filament colors I have. While there are too many colors for me to list, some good alternatives for the background include purple, galaxy black (flat black with silvers speckles), white marble (a light gray marble/stone looking color), gloss black, or whatever else I have.
I'm selling these for $20 per pair including US shipping. If interested in purchasing, please PM me.
