Has anyone purchased small ball-and-socket joints from Alibaba before? They usually require a minimum quantity of 500 units so I'm looking to see if anyone knows of a wholesaler or retailer that sells smaller quantities of similar items.
Here's the Alibaba link as a reference.
I don't think those joints are designed to be tightened up so they hold their position. They are most likely to be meant to move freely. I've used the balls from carburettor linkages that were like that - the ball was free to move in the socket when used on a carburettor. For armatures I was able to use just the ball, which had a threaded shaft on it, sandwiched in between two aluminium plates which I made myself, with tension screws near each end to tighten the joints up so I could animate with them.
idk, but i ordered about a week later this balls https://ru.aliexpress.com/item/NEW-16-x-10mm-M4-Threaded-Stainless-... and awaiting for it, and ofc they can be purchase for small amount, i ordered a 96 balls for 15$~ :3
and the sockets can be DIY easily from a lot of materials, i'm going to buy brass bars and cut parts out of them.
u can do it too ;)
