Parts, tools and all activities required to make your own Camera Dolly for your actioncamera like GoPro, Actionpro or any other video camera / DSLR that support standard tripod conector. Camera can be attached directly on the Dolly or attached to a tripod head. The last one is the best option as will allow quick camera repositioning.
The actual name of this is Table Dolly, as it is a small one and not really a full size Dolly, but this is an essential part that can be turned with minimum effort to a slider or tripod slider. DIY clip for this kind of transformation will come later.
