Micro Quad Racing Gate

Unlike my first design, this time I wanted gates that were totally 3D Printed (because, you know, 3D Printer!). The only items needed that aren't 3D Printed are 1/4"x1/4"x1/4" Neodymium Magnets which cost about 20 cents each on ebay (and I'm sure multiple other venues). The magnet is a press fit, but obviously can be glued in as well. The reason for the magnet is that most open doorways (at least around here) have a metal corner around the perimeter. Also, the magnets stick to drop ceilings. Who
