Plate with clip for Matek f405 flight controller, nice tight fit, 4 holes 5mm diam. to fit shock absorbers.
Need to remove memory card before sliding in flight controller.
Designed in FreeCad 0.18, source file included, feel free to modify.

EDIT:
uploaded a new (V3) version with:

• extra mounting holes, just use the fins you need and cut-off the rest if there is no space for it.
• slightly longer channel for the FC plate
• extra SD card slot for 180 deg FC plate mount

Source file attached, feel free to modify but please post your make/remix/comment

print with support (everywhere), FC slot might need touch of file/sanding if fits to tight
