I'm having a lot of trouble figuring out how to work entity manipulators. The only tutorial I can find uses outdated coding from 2017, and hardly any of it is the same now. I ultimately want to make it look like an ironsides Dalek holding a tray of tea with its head turned to the side, but I can't figure out how to add the prop after changing the variant. Could someone give me some pointers?

They no longer hold the tray I'm afraid 

Well that's rubbish. Oh well.

Hello, that's probably my video that you're referring too. I've had so many requests to make an updated one that I think I will record it this weekend and try to have it up early next week. I was going to record some other things, but you just convinced me that this is more important.

Yes! Thank you! That makes me beyond happy. Currently my entity manipulator is sitting in my cloister room in the form of the Ender Dragon.

I just uploaded it, here's a link: https://www.youtube.com/watch?v=W3iVAO_xPGw
