I will not lie - the supports can be a pain due to the small size and the threads - only need supports from the buildplate for the screw in end of the top. I used tree supports and after removing what I could I just screwed it together a few times and it worked perfectly.

I added a screw adapter to make it very steady without having to glue the two pieces together.

I made the threads small so if you needed a bit more height you only would need to screw it in so far and would not need to redo the whole thread pattern or else cut and extend the base.
