This is a vertical mount for the HDHomeRun Flex 4K. It has hollow hexagon connectors attached to it. The mounts are 4 hexagons apart (2 blanks between them) and fits wonderfully. Designed to be attached to the Honeycomb Storage Wall.

I printed in .24mm layer height with base plate supports for the connectors.
The print fits the HDHomeRun Flex 4K snuggly, but it will still slide out by pushing through the opening at the front.
The author remixed this model.
I used the hollow connectors and attached them to a mount to hold my HDHomeRun Flex 4K TV tuner.
