This is the simplest and most straightforward microphone adapter for the Canon M6 hot shoe mount. Used the template from the remixed model and the cold shoe, linked together. PLA works well with Rode Videomic Pro.
Background - I have tried all possible adapters, including cages, but they are all too heavy and bulky, for something that should be as simple as this adapter.
Note that the clearance of the bottom of the screen is minimal, so even with this fairly thin adapter, a little bit of the screen is blocked. In the latest version of the STL model uploaded, I've made a notch on the screen side that reduced the blockage.
This is best printed upside down with supports on the coldshoe extension area. It gets a little tricky to clean up the support material, but I have been able to clear it with a flat-head screwdriver
The author remixed this model.
