This is a rail attachment I made to connect my 3DMakerPro Seal Lite 3D scanner to a 1010 rail extrusion. I am working on a rotary system that will allow the part to stay stationary and the scanner move. It fits the rail quite snugly and depending on how you postcure (if you use SLA like I did), it may be a little too snug. It may take some light sanding and some lubricant to have it slide easily.
