I got permission from the boss (wife

So far, I got the t-slot bars, nuts, and screws because I got an awesome deal on eBay ($32 shipped for all of it). Next will be the laser cut parts when they become available.
One thing I noticed while going through the BOM is that there are a couple parts not available (or coming soon) in the shop. The most important would probably be the eccentric cam since I can't think of a way to use something else. Are there plans to add those to the shop?
