NOTE: YOU NEED TO MIRROR THIS FOR THE 2nd SIDE.A simple holder, you can use a ¼" or 6mm steel rod or upside down end mill to hold it in your spindle and then clamp the dovetail of your test indicator to it as well. Best to position the holder as close to your collet as possible.Spin it (by hand only!) to X+ and X- to see whether your spindle is trammed. The reading has to be the same both sides. If not, adjust tram and repeat until they are the same. Repeat for Y.To print, you need to duplicate the model and mirror the duplicate. In Cura, right click and select multiply selected. Specify 1 and click OK. Then select the duplicate and hit M for mirror (or use the icon menu on the left) and click on the RED arrow to mirror it. Look to be sure the holes and dovetails align then print.There are two versions, one for M3 and the other for M5 hardware.Printing:I printed in ABS with 0.4mm nozzle, 0.2mm lh and 120mm/s speed. No supports.
