+// major issues with rev 3
+
+// - motor side screw hole conflicts with switch / other rear mount is
+// inaccessible without removing the leadscrew from the nut
+
+// - New idler anti-pitching ribs are too big (new idler I wasn't
+// using is larger so the existing ones worked fine for that one...)
+// NOTE: new idler is meant for integrated toothed idler...
