So I just got back into 3D printing been away a year from it due to being frustrated with my print and all the hassle it was to fix a whole host issues. Long story short didn’t want it to be an expensive paper weight so I went back to it with some help and here I am at with this IG11 figure(Link). So I already printed the shoulder joints and everything for this figure but I am having a hell of a time attaching the said figure joints together. Is there any way to attach them aside from heating b/c friction and pushing aren’t working. Your advice is welcome.
