Echo Show 1 (1st Gen) rotating stand with self-made ball bearing

thingiverse

What you also need: 8 steel balls diameter 6 mm, 4 or 5 self-adhesive rubber feet (so that the bottom part stays firmly on the table when turning the Echo Show), plastic glue, grease (optional). First print only the lower part and the upper part. Then temporarily assemble the two parts together with the balls in place. Depending on how accurately your printer prints, the cylinder of the lower part will then be approx. 1 to 1.5 mm lower than the recess in the upper part. You must then adjust the height of the inner cylinder of the retaining plate in the slicer so that both parts are firmly connected after gluing together, but can still rotate freely. You can add a little grease to the ball groove before gluing the whole thing together. This is not absolutely necessary, but prevents any squeaking of the ball bearing during rotation.
