This mod is also detailed in the Kiss Mods thread but thought to give it, it's own thread.
It is the Classic Marshall Amp & Quad Speaker plunger plate that fits into the recess of the plunger plate and suits both the Stern and Williams plunger Mechs. Marshall has given me permission to use the logo so their is no copyright in using the logo - simply a portion of the sales will go to a worthy kids charity.
The 3d printed multi-coloured Marshall Amp Plunger Plate came today and looks great, just needs a quick clear coat and install into the recess which will be ideal for the band pins like KISS, AC/DC, Metallica and any others. Shapeways is working on offering the clear coat service but still 6 or more months away.
