**edit 17-5-15** refreshed an old thread as this mod should nicely and should be a nice scale in the Pro KISS at the back of the Star Child area towards the back of the playfield. The 4 quad speaker holes can be back lit as well. Have sold a few via Shapeways recently gearing up to the KISS Pro.
Here is a mod I have been working on and went through a number of versions of the 5-6 weeks.
It is my version of the well known Marshall - Quad Speaker with the optional Marshall Amp. I have proven it works through 3D printing at home but I can't achieve the quality I want at home due to over hanging edges and the fine logo detail etc. This mod will be a purchasable item from Shapeways (3-6 parts) which will suit the US guys and with the Aus guys I can get a few and then on sell them but people will have to pay me first and be committed.
I have taken the leap and ordered 1 full set of parts to be made and sent to me to determine if they can actually make it and that it all assembles correctly and looks good.
The beauty with Shapeways is that some of the parts can be ordered in various metals - which lets you customise your speaker.
The speaker cabinet, amp cabinet and speaker grill are all the basic glossy black but the personal touch is the Marshall Logo and the Amp's knobs and switches. I have ordered the logos in a polished SS and the knobs in a polished gold metal. What is also cool is that I designed this item to install real fine speaker cloth into the speaker so it looks real. I will leaving it to you guys to install where ever you wish and supplied a single hole in the base for mounting, but you can always drill a extra hole if required (carefully). In addition the speaker grill has the 4 quad holes and if you install a flasher inside this will project through the speaker cloth.
The size of the speaker mod is 55mm wide x 50mm high x 24mm deep
The size of the amp mod is 55mm wide x 20mm high x 20mm deep
You will be able to just buy the speaker parts and if you want to go for the amp as well you can. But once you install the amp into the top of the speaker you will not be able to separate them without having 2 holes as I designed it in a way that material presses out to insert the amp locator plugs.
Lastly - with the parts I have only put a small margin to cover my design time, BUT with the Marshall logo I did not assign any margin at all as I don't want to be making a cent off someones design, what you will be paying for is purely Shapeways manufacturing cost to make it which for SS is $6.38.
With the last image ignore the print colour as the final version will be black and much finer in detail.
