I modified Jacob Thompsons Arducam case to make it the same height as a gopro mount. Then I added the gopro compatible legs for the bolt and mirrored it. this fits perfectly with the Arducam 8k that i got from Amazon (https://www.amazon.co.uk/dp/B07YHJK4LN?psc=1&ref=ppx_yo2ov_dt_b_product_details&tag=coa_gb_g-21)
The author remixed this model.
