Mini Drak Nose Camera Mount

thingiverse

This version divides the mount into a base and cover. The base is bonded with adhesive to the mini drak after cutting off the nose. The cover screws to the base with three M2.5 screws (about ten to twelve millimeters long is plenty). The hex nuts are captured in the base and should be glued in place so they don't slide away from the hole. I use nylon screws and nuts to minimize weight. Rev B moves the location of the split closer to the rear of the aircraft, allowing both cameras to be removed through the front when the cover is unbolted from the base. You no longer need a large hole behind the foxeer camera; just a tunnel for the camera cable into the bay. This mount is designed for the foxeer 1177 with two point five or two point one millimeter lens (or any narrower lens will work too) and the runcam2. The reversed files switch the orientation of the cameras (from the original design shown in the photos Edit: First two photos show the reversed prints as of four twenty-one seventeen) and put the runcam2 on the right side of the plane. This makes it possible to remove the runcam2 rear cover without removing the runcam2 from the mount since the rear cover will slide towards the center of the bay to unlock. Update April fourth two thousand seventeen Added cover with top support hole for airspeed sensor. It's designed for the MFD airspeed sensor, which is just a single small two point five millimeter diameter tube (the static port is uncovered inside the aircraft in the new MFD airspeed sensor). But I left enough room that this hole can be drilled out for any diameter pitot and plenty of space for it to protrude so the side holes remain uncovered and still be ahead of the cover for uninterrupted airflow. Update April twenty-six two thousand seventeen Added one piece file back for those who don't mind cutting enough foam to remove the cameras through the bay instead of having the bolted on front cover. Update May third two thousand seventeen Added one piece file with eighteen millimeter hole for FPV cams such as the runcam swift. Installation: The foam cut is seventeen millimeters forward of the leading edge of the center bay cover indentation. Or seven millimeters forward of the leading end of the top fiberglass spar grooves. Be sure to cut perpendicular to the seam in the side of the fuse top to bottom. And keep it square when looking from the top or your cameras will be looking left or right. Then you'll have to hog out a big square all the way into the bay to provide clearance for the runcam2. Best to use a flat razor for this and be sure to keep the seven degree angle (by eye is good enough). You can also put a hole through the top of the bay lip (just under the cover) on the forward right side to access the runcam2 power button. You'll be able to figure the location when you have it assembled. Use the base print to act as a template for the runcam2 hole into the foam through to the bay and also to locate the camera cable tunnel for the foxeer. You will want to put a small drop of goop or hot glue on the foxeer at the front to hold it to the base print prior to putting on the cover, since the foxeer could move backwards which would not be desired. A drop on each side flush with the face of the base print and just touching the camera body will be enough and easily removable if you have to take out the foxeer for some reason. Update April fourteenth two thousand eighteen Added cover file with eighteen point four millimeter diameter lens hole. Update April twenty-third two thousand eighteen Added cover and base file for split version of one hundred seventeen seven camera only, no HD. Note it's important to print base in orientation as saved with supports. You can clean up the supported area until the camera fits well. This way the seam will be cleaner. Update October twelfth two thousand eighteen Added one piece version of one hundred seventeen seven camera only mount.
