Dial test indicator clamp for the Solidoodle 3 based on previous designs but with two DTI attachment options. This stl file provides an 8mm mounting hole for the DTI in a central position between shafts and a second bracket to mount the DTI as shown in the jpg image. I have included an igs version of the model so that it can be modified to take different DTI's and or Magnets. The magnets for this model are 10mm x 1mm. The best way to mount the magnets is to use Acetone and a clamp. Acetone is readily available through Ebay. Just drip a small amount of acetone into the magnet mount hole and locate the magnet, clamp in position and leave for about 1 hour. Added picture of clamp in location, move clamp by hand in X direction and using motors in the Y axis.
