While the original was excellent, it posed a problem as I had to use my firing hand to turn the GoPro on before drawing. Now I can use the index finger on the support hand to turn the recording on.
Recommended print settings are the same as original. Organic supports are handy to save filament.
Filament used: Devil Design PETG in Olive Green
The author remixed this model.
Detached the mount part, shortened the whole thing from 82mm to 54mm in height, and re-attached the mount. Widened the gaps a bit to make the GoPro easier to install, the original gaps were a bit too tight and required filing to open them up.
