tube joint

This resin printed single axis joint uses a high quantity of resin and could further be optimized to save resin.
The sleeved end slips on to a 2.5 inch OD aluminum tube.
There is a central support which can be removed by rocking and twisting.
Supports from the base to the inner and outer sleeve tubes are a must.
there is a through hole in each of the halves to allow wire running through

there are two versions of the joint. Each has a different range of motion
The diameter of the pivot hole 19mm.. if remember right, I will check and update
I chose to machine brass bushings to press in and add a central pivot point as to not wear the print.
