This list is a best attempt at identifying suitable parts for this project. Some things might be missing or extraneous!


When I link directly to a part, I am simply indicating which part I used, to the best of my documentation or recollection. This is not a 'kit', with all parts collected and gauranteed to work together. In most cases, many parts will work, however, some editing of the laser cutting files may be required. In just as many cases, a subtle difference between one part and another may cause the part to not fit. It can be difficult to determine that you have the 'right parts' without ordering things and trying it out.
