Eachine E013 frame

My version of the frame for the eachine E013 drone.
Original frame weight is 3.89g, my (without battery frame) version is 4.00g.
The idea of fixing gum is honestly borrowed from this model - https://www.thingiverse.com/thing:2753175 (good idea!).
Two versions: with a frame for the battery and without it.

Optional - motor shields.

-------------------------------
Parts of the frame for the battery are printed and glued with Abs plastic, which must first be dissolved in acetone.

EDIT:
28/03/2019 - New v2 version. It's a bit heavier but much stronger in the diagonal connection of the motor.
