I finally have useable examples, the PETG has a bit much stiction, but will probably work. The ABS did split as well, but only the lowest part, which may have just needed more heat, but its still a usable piece.
Made another set in ABS last night, it still split, but I carefully acetone welded it back together while making sure the nozzle didn't fuse to the base. It looks to be the best result of all the attempts so far.
