This was my attempt to print off a replacement knob for one of my lamps, its a standard lamp I picked up at Walmart some years ago. This knob fit on perfectly. I did have to drill out the hole a little because the support material would not come off and impeded going on the lamp. I printed this at 100% mainly because I have children and did not want it break. I've included the Solidworks files in this print so that if anyone wants to modify this they can. My top layer did shift but I think that was a problem with my printer and not with the file.
