This is a cage for the never old, and still crazy good, Panasonic LUMIX GH2.
I was never able to find a professional one here in Italy, so I designed one myself with a crazy lot of trial and errors. (almost a spool got wasted in findings the right size)
I printed it and it's working very good for me.
This print use a lot of 1/4-20 to 3/8-16 bushings, because threaded PLA is not strong enough for normal use.
If your printer setup is spot on for threads, you can simply screw the bushings on the cage in any hole you need, but mine is a little sloppy on threads, so I tapped every screw hole with a 3/8-16 Tap.
In total you need 20 bushings or less, it depends on how many screw hole you need.
The camera is screwed directly on the cage with a simple 1/4-20 D-ring camera screw, then under the cage (or on the side), you can fix a quick release plate of your choice.
In my case I use exclusively Arca Swiss.
As you can see in the photos, this cage can handle some heavy accessories without bending. I used ePLA-ST from Sunlu, because is crazy strong and rigid, but I suppose any good brand PLA+ or Carbon, will do.
The little piece that goes in the hot shoe, dont need a bushing, since I forced a short screw directly in the hole.
