  • 3D Printed Modular Cage for Blackmagic Bidirectional SDI/HDMI Converters

    January 8, 2021

    Stack of Blackmagic converters

    This modular cage allows you to stack Blackmagic Bidirectional SDI/HDMI 3G Converters on a desk or behind other gear.

    The design is composed of four parts: the main shelf, the top shelf, a top plate that sits on top of the top shelf, and an optional angled base. The angled base plate lets you mount the whole stack on top of rack gear that's mounted at a 9° angle, such as the StarTech 8U desktop rack. You can print as many of the main shelves as you need to stack.

    The shelves are designed so that the converters can slip in from one side with enough of a gap on top to be able to insert and remove them even after a stack is assembled.

    If you'd like, you can glue the stack together to make a solid structure. Otherwise the pegs are long enough that the stack is reasonably stable even without glue.

Hi, I'm Aaron Parecki, Director of Identity Standards at Okta, and co-founder of IndieWebCamp. I maintain oauth.net, write and consult about OAuth, and participate in the OAuth Working Group at the IETF. I also help people learn about video production and livestreaming. (detailed bio)

I've been tracking my location since 2008 and I wrote 100 songs in 100 days. I've spoken at conferences around the world about owning your data, OAuth, quantified self, and explained why R is a vowel. Read more.
