<p>What I changed</p><ul><li>I did not want to paint the hour hand.<ul><li>I split the hour hand from its gear so I could print each in its own color.</li></ul></li><li>I did not want to glue the gear train together.&nbsp;<ul><li>I added a pin hole at each glue point and inserted a sewing straight pin cut to appropriate length.</li><li>I added a threaded extension to gear3 to attach another M3 nut to help weight the gear train down.</li></ul></li><li>I wanted to block the bright red LED at night.<ul><li>I designed a cover to fit over all of the electronics.</li><li>I mounted the Nano to the stepper board with a small piece of PCB board with holes in it to mount to the cover.</li><li>I made a box area to hold optional 9V or 6V battery.</li></ul></li><li>I needed a tighter fit on the stepper motor gear.<ul><li>I made a slight dimension change to the shaft opening.</li></ul></li></ul><p>Shiura uses Blender; I use Fusion 360. Fortunately, I was able to import the key parts of his design so I could make the tweaks.</p><p>The print times and print files are only the changed parts. All other parts are original and not included here.</p><p>This is an excellent design and I had a lot of fun making it and modifying it.</p><p>&nbsp;</p>
