About This File
This gear and pinion is designed to fit a Lazy Susan which has a diameter for the inner ring of 415mm. This Lazy Susan is the perfect size to be used on an NSD dome. it may work for other domes but I've not tested it with anything but an NSD dome. You'll need to print 2 pieces of both the "A" & "B" parts. the ends have lap joints for stability and the countersunk holes are for 10-32 size bolts. the height of the gear has been designed so that you can leave the rubber feet that come with the lazy susan on the inner ring in place and the gear will be the same height. you will need to drill holes in the gear where your rubber feet are so it will sit flush with the bottom of your dome rotation plate.
Note: the picture shows the gear sitting on the top of the dome rotation plate but that was just to take the picture. the gear is mounted on the underside of the dome rotation plate which is why it is the same height as the rubber feet on the inner ring so it sits flush
