Had to create the bottom as one piece. Was struggling to fit the mount into the self-standing bottom. Created the nuts and bolts with the Nut Job Thingiverse customizer!
How did you combine the Go Pro mount with the bottom self-standing bar? I would like to do the same as your great idea!
I merged the two parts together in Tinkercad. You're welcome to it here:https://www.dropbox.com/s/cne2as6k9byan6e/gopro_bottom_tinkered.stl?dl=0
Thank you so much, it will be much sturdier now! I'll have to share the finished product
good work mate.
