@zenbike is one of the good guys and he went above and beyond for me. I was interested in some 3D printed scope rings to test various scope heights before buying new rings. I do not have a printer so zenbkie offered (I didn't ask) to print some and ship them to me. He only wanted material and shipping costs but I pitched in more for his time and effort. Not only did he do it, he had them at my door in a few days!
