I need another model.
This time its simpler but it comes in 2 parts, so i will need 2 models.
Basic dimentions are there.
Again its a pipe, but the two pieces screw in or connect together and piece 2 can connct to itself (so you can keep connecting them)
Im not sure what is better a thread or some basic male/female connector. as the wall thickness is 3mm overall.
If you have a basic "click and twist" connector you think will work better, you can use that.
im not sure a 3d printer can print a thread very good.
