This is my first ever 3d design using 360. I designed this cupholder tray for a mahjong table, that you can also use to put poker chips and also your phone while playing. Diamater of the cupholder is around 95mm which can perfectly a water bottler like an owala, i added a slit wherer a handle for a mug can fit. Screw holes are chamfered to a allow a flushed fit when screwed using flat countersink screw.
