Dominoes Box

I acquired the following parts: • One N20 100RPM gear motor. • One twin AAA switched battery pack. • Four 8mm ID, 16mm OD, 5mm thick flanged ball bearings. • One 3mm diameter by 1mm thick neodymium magnet. • One lever switch (CYT1073). • One reed switch (EK1621, 14mm by 2mm tube). • Two M2 by 20 cap screws and nuts. I 3D printed the following parts at .1 mm layer height, 15% infill with no supports in PLA unless noted otherwise: • Two “Axle Sprocket.stl”. • One “Base.stl”. • One “Belt Support.stl”. • One “Belt.stl”, TPU. • Eighteen “Bolt (M8 by 1.25 by 8).stl”. • One “Bolt (M8 by 1.25 by 14).stl”. • One “Cover.stl”. • Seven “Domino Mount Axle.stl”. • Seven “Domino Mount.stl”. • Seven “Domino.stl”. • One “Front.stl”. • One “Motor Mount.stl”. • One “Rear.stl”. • One “Reed Switch Mount.stl”. • Two “Sprocket Cap.stl”. • Two “Sprocket.stl”. • One “Top.stl”. This is a high precision large format 3D print and assembly model using at times very small precision 3D printed parts in very tight spaces. Prior to assembly, test fit and trim, file, sand, polish, etc. all parts as necessary for smooth movement of moving surfaces, and tight fit for non moving surfaces. Depending on you printer, your printer settings and the colors you chose, more or less trimming, filing, sanding and/or polishing may be required. Carefully file all edges that contacted the build plate to make absolutely certain that all build plate "ooze" is removed and that all edges are smooth. I used small jewelers files and plenty of patience to perform this step.
