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 screws straight into the TPU as Mr Shen intends for it to be, but if you would prefer to use 8mm standoffs print this version: https://www.thingiverse.com/thing:3598191
Regarding print orientation, please see the attached image; printing it in this orientation 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).
