In the USA, brooms, mops and paint rollers use ACME 3/4 - 5 screws (handle male, attachment female). Likewise, camera tripod mounts use 1/4 - 20 screws. This model provides an adapter that allows small cameras with standard tripod mounts (e.g, the Insta360) to be mounted to broom handles or similar. In this pictured case, a telescopic window cleaning handle is used to make the World's largest selfie stick.
Necessary hardware:
1/4" - 20 screw (0.5" in length)
The author remixed this model.
Extended length of female mop screw adapter, and added a space for a recessed 1/4" - 20 hexagon nut and bolt.
