You will need the STLs printed (all of them should print without support besides the GoPro mount) plus: - one 608 ball bearing - 9 M8 nuts - some M8 washers - an M8 threaded rod, length still tbd - I think it will be around 40 cm - an M8x100mm screw for the handle - four M4 x 20 mm screws (you will have to trim them so that there end will be flush with the top of the locking nuts) - four M4 self-locking nuts - four M4 washers - some big washers as a weight (I used 10 with a 13 mm bore, so I used the "Weight tube" printed part to center them)
