Joza TX130 quadcopter frame

After fooling around with 5" and a whoop, I decided to build a 3". But what fun would it be to design my own frame? Well, it worked out awesome.
The frame is a TrueX, 130 mm motor to motor. Overall weight (including props, battery strap, FullSpeed Lucky Box buzzer, no battery) is 88.7 grams.

It is designed for a 20x20mm stack. Bottom plate is to be threaded M2 to alow for the stack mounting. Or you can enlarge the holes and use nuts.
Front and rear stand offs are to be threaded M2.

I have had the plates cut out of 3mm carbon fiber plates. 1,5mm for the top plate. Stand offs are printed.
