I made these two GPS mounts for me and a buddy. We both used the GepRC M10-DQ GPS modules. He has the AOS 7 V5 frame and I have the GepRC Moz7. The Moz7 also needed a rear antenna mount so I added that too. you just need to bend the mount to slip the antenna in and then it's not going anywhere. Otherwise the GPS module also just slips into place and should be fairly secure. It can fall out if you crash, so just don't crash. It also has a spot for cable management under the mount, you can cut the two tabs to make flaps and slip the wires in that way so you don't need to unpin the connector. 

This should print perfectly fine with TPU with no supports! I recommend printing with solid infill and the GPS should fit in there pretty snuggly.
