GPS mount / holder for F450 F550 S550 multicopter frame

Last crawled date: 4 years, 3 months ago

This is for mounting a round GPS / compass module on the top of the (Chinese) F450, F550 and S550 multicopter frames. The distance between these two holes measures 64 mm (F450) and 100 mm (S550). The feet for S550 use two screws per side, the ones for the F450 only one screw per side.
Screws are M3 including a nut and if possible a washer from the bottom side.
The "cup" holding the GPS module is also screwed down on the "girder" with two M3 screws and a matching nut. Make sure to use stainless steel, brass or plastic screws and nuts or some other non-magnetic material for this! Otherwise the compass part of the module will most likely not work correctly. One of the cup models has a 19 mm notch in the middle. Besides that, they are identical.
Instead of printing pillars, I used 8 mm (outer diameter) aluminium tubing and a bit of force (soft faced hammer) to put them in place. It's a very tight fit. Carbon tubing should work too.
Since printing the parts for myself, I've added some recesses on the cup parts, to make it easier to remove the module from the cup.
UPDATE: Added a single feet base plate with custom holes and an adapter to attach the "cup" to a single 8 mm aluminum tubing.
