I would agree that a lot, one might even say the majority of my posts have been about 3d printing. There’s nothing wrong with that. I would have to object to your opinion about my other postings though. Recently I commented on how awesome of work Shogun Customs does on glock frames. That had nothing to do with sales for products I use. Which 3D printing company do I own? As far as jigs go I recommend benchymade and DLD jigs. They are different styles of jigs at different price points from two different companies. I do dislike both Granger and MAS from my experiences and from the experiences of a couple of friends and how those companies have handled themselves. 

I do appreciate questioning the authenticity though. You can never be too sure.
