GoPro Hero 9/10/Hero Black Bones adapter for Camera Butter ND Filters

thingiverse

This is an adapter to use Camera Butter stick-on filters on the GoPro Hero 9, 10 and the GoPro Hero Bones. Camera Butter already makes twist-on filters for these Cameras, but with this adapter you can use the stick-on filters made for the Hero 8 on the 9,10 and Bones. This is especially useful on the Hero Black Bones, as this adapter with a hero 8 ND filter is about half the weight of the regular twist-on filters made for the 9/10. Print in PLA or in PETG. You may have to adjust the extrusion multiplier if the filter is too tight or too loose on the camera. Use these stick-on filters: https://camerabutter.com/products/gopro-hero-8-nd-filter And stick them into the adapter. To put on the camera, take off the stock lens cover by twisting, and put this on the camera with the "grips" facing left & right, push down and twist 90 degrees. If you have problems getting it on, then it's likely that you have some residual supports left inside the connectors and you need to clean them out. Print out one of these for each filter you have to make them easy to put on & remove. NOTE that this lens cover is NOT waterproof - don't use this under water!
