Micro Quad Racing Gate

I've got these neat micro quads all set up for FPV that I've been flying around the house. I wanted to "add" to the enjoyment, so... I jumped into Blender and drew up some connectors to fit some el cheapo, sub 3 buck, 7.3mm diameter Wally World carbon fiber shafts (I used these same shafts in the 3D Printed lawn spinners that I drew up). It took two shafts plus 4" from a third to make one gate - 4 pcs @ 10" and 6 pcs @ 4". So the next few gates will only take two shafts plus leftovers from that
