Awesomesauce jonniemac!! And what makes me drool is that you did RED! I love RED
mods.
I think it's great that you are sharing the CAD files with other modders at no charge, but the downside is those who make a profit off your work - those who will use it to make and sell
mods and those vendors who will sell
mod kits. You may even see your work listed at shapeways by someone and with a markup on price.
It's sad and unfortunate and absolutely not right, but this happens. So I would hope that you re-consider and take down the free CAD file, list it on shapeways yourself and with a markup that you are comfortable with.
