Have design you want printed? or found something online you want? we can provide the service of printing it for you. Just email the STL you want printed and we can give you a quote on the cost to make it happen. Even if it has a copy write but is made available to share for personal use we can provide the service of making the print for you because it's the service being sold, not the part.
Have a part that broke? As long as you have all of part that can be assembled as if it were whole we can duplicated it. There is a cost for the time to design and then a cost for the print. Once the design has been made, we will always have it to reprint more of the part going forward if it's needed for just the cost of the print! or by multiple for back ups.
You have your own design or want us to make a custom design, you can send me sketches, or measurements and a drawing and we can figure out what you need and what to print. much like replacement part there will be a fee for design but once the design is made, you can request additional prints at any time for just the cost of the print.
