This does fit XTool D1 Pro
I tested the camera before assembly of the arm and found it didn't work. I took it to my work bench and gave it a once over but nothing stood out. Having experienced many electronic components from China I know there sometimes are problems with assembly. I took a dental tool and pushed all the wires into the JST connectors and resolved the problem.. I went one step further and hot glued the connectors together and the wires. Less chance of the small components from vibrating apart.
As for the arm structure, it goes together rather straight forward and it built very well. I would say it is almost over engineered for the purpose of holding a small camera. Overall, it should perform very well and last a long time.
Easy to assemble the stand and quick setup using Lightburn. You do have to get use to viewing the sideways image but after using it a few times, it become natural.
Been very happy with my large enclosure. Assembly was a breeze and the unit is well built. The only drawback is the color of the viewing window. I wish it had been laser filtering but a minor inconvenience. I'd recommend and buy it again in a heartbeat!
Well made, good value.
