This part allows you to mount a TBS style SMA connector to the rear of the ShenDrones Ichabod Junior at a 45 degree angle. This version enables the use of 8mm long standoffs to separate the plates - I have also uploaded a version for screwing straight into the TPU as Mr Shen intends for it to be: https://www.thingiverse.com/thing:3598234
Regarding print orientation, please see the attached image; printing it with the holes for the standoffs at 45 degrees eliminates the need for a lot of the support material and should make the resulting part much cleaner. Don't forget to ensure that overhangs of up to 50 degrees are not supported in the slicer :)
Print in TPU - I recommend Sainsmart TPU (which is what the majority of miniquad parts are printed with).
