Slim 6 Way Wooden Train Turntable

My 2 year old is super into Thomas/Ikea/Brio wooden trains, and we bought a Frankenstein collection of tracks, but we didn't have a turntable. My MP select mini v2 only has a 12x12x12cm print bed and couldn't fit any of the available designs. So I designed a new slimmer version with 6 tracks. The asymmetric base is only 11.3x10.8x1.2cm, and the symmetric base is 11.7x11.3x1.2cm. The tops should fit both base versions with good connection and spin. Tops are 69mm diameter and should spin one stand
