Giàn quay orbital đơn giản

This design uses a selfiestick with a ~32mm Ø handle. The bottom part needs an M6 bolt to be glued in place. The top part can be attached by preferably using a self locking bolt. There are no bearings, if you use o-rings and some lube the force required can be tweaked with tension on the bolt. The movement is quite acceptable. It is sturdy enough to use with your phone. The rig attaches to your tripod using a standard 1/4"-20 UNC camera attachement (the little threaded nub on your tripod platform).

This thing will probably not win you an Academy Award for best cinematography but it is adequate enough for your sporadic orbital vlogging shots.

Use PETG if possible. The filament in the images is Jayo High Speed Matte PETG.
