If you have watched any clips at the top of my page http://www.lanestrains.com/SolidWorks_Modeling.htm you would see how these items are formed.
As the laser is moving around some of the first things that formed are supports. They probably look a lot like the mounting pins you are asking about. As the item is built these supports hold the still very fragile item in place. Since the best surface is always "up" the "worst" side is always down - which in the grab iron case includes the wanted mounting pins. They have to be removed from the machine and cleaned up to get the supports removed with some sanding. Hopefully no pins get broken there. I get them to my caster. He makes the mold. Hopefully no pins get broken there. He casts them. Hopefully no pins get broken there and I get a complete item. So I tried my best to make an exact replacement but there is only so much I can do. This process is not injection molding of plastic. Lots of things beyond my control have to go perfectly. And since the master patterns are in a box heading towards my caster there will be not changes at this point.
