Mirror Accessory for Canon 6D

thingiverse

I use my Canon DSLR for astrophotography. The problem is that while my camera is pointing up, the LCD screen is pointing down. My Canon 6D doesn't have a swivel screen so I have to crouch or get down on my knees to frame and focus the subject. It's awkward at best, so I made this thingy to attach a mirror to my camera. The three pieces form a z-fold so that the camera can be rotated 180° and the mirror can still face upwards. You can forgo the middle frame if the camera will never be inverted. The mirror mount attaches using the ¼-20 mounting hole on the camera body. In astrophotography, most DSLRs don't attach to the tripod directly so the hole should be available for accessories such as this. I created the FreeCAD files specifically for a Canon 6D but they can be modified for other cameras. I think that in most cases only the bottom plate will need modification. The thingy folds flat up against the back of the camera or even into a small padded envelope. It's very light but correspondingly, a little fragile. I intended this to be a prototype for a stronger version but with a little care, it has worked well enough that I'll just continue to use it.
