This a box to protect & mount a mavlink-OSD / minimOSD unit to a model.
Mavlink OSD is an "on screen display" electronics module used to annotate flight & model status parameters over the live video feed.
There are numerous versions of firmware that can be used on the board.
ie : KVOSD, MWOSD
This unit is the same dimensions as my Ublox GPS case.
You can use it with it's lid or stack it under the GPS case.
Screw holes in the case are 3.2mm designed for 3M metal screws and in line with the GPS case so you can run screws through both units to secure them in a stack.
There's additional holes for recessing screws as an additional mounting option.
PLEASE LET ME KNOW IF YOU FIND THIS USEFUL.
I'm also interested in what firmware is most popular for OSD.
printing the base requires supports for recess under base to hide screws..
The lid doesn't require supports.
I printed in ABS but should be fine with PLA.
FreeCad.. FreeCad is Awesome.
