Made for the tbs source one, but could probably be used for others. the standoffs are 20mm apart and 5mm in diameter. Which is a very common rear standoff layout. All files can be uploaded to one print bed and can be printed in place without standoff . The RX mount might get a little hot toward the top and melt so go slower toward the end of your print, unless your printer is set up perfectly to print anything. This is just a basic universal VTX, RX & GPS mount set.
