SummaryTic-Tac-Toe Machine enclosure I'll add the link to electronics and assembly guide when I post it.Print SettingsPrinter Brand: MakerBotPrinter: MakerBot Replicator 2XRafts: NoSupports: NoResolution: MediumInfill: 20%Notes: No rafts or supports, just print the box upside-down and lid with wider side down. I used 15 outlines-wide skirt that touches the modes to minimize the risk of peeling off the plate because of the size, but if your printer is well-tuned, you don't need that. Kapton tape would add glossy finish to top and bottom which looks pretty good with arcade buttons.Post-PrintingNo finishing is necessary, just use a knife to remove the skirt, if you used it.Tic-Tac-Toe Machine in actionHow I Designed ThisI used Autodesk 123D Design, see a model attached. Enclosure is quite tight, if you want it easier to assemble, just make the box taller. P.S. I printed 7 prototype pieces (see last image) before it was good. Actually, last run was also a prototype as chamfer on screw holes was to low and I had to use knife to adjust it before updating the model.
