About this 3D model
This object was made in Tinkercad. https://www.tinkercad.com/things/eWRmN4mpDDc It is a pool bridge or spider, 60mm wide, suitable for a small pool or snooker table. The shaft hole is 11mm diameter, should suit a lot of cues. I printed this in FormFutura EasyWood Ebony. Looks good to me.
