I’m working on printing an ABS spool holder for the FF Creator, but the curved sections are killing the print again and again.
I’ve tried changing the temperature of the HBP and the extruder, but I can manage to get around the problem. I’ve also tried to slow down the print, but it doesn’t fix the problem. These are some pictures of a representative specimen:
I appreciate your help. I’ve gone up and down, but all I’m doing is getting nowhere. Thanks a lot!
What layer thickness are you running at?

I am not sure I have understood the problem, but I think that it is just a question of supports: printing a vertical circle above the ground is very difficult for the printer, especially the first part (remember the 45° law: you should put supports under everything which is less than 45° respect to the ground), so I think you should just put some supports under the curved part. Hope it solves your problem, let me know! 
P. S. Sorry for my bad English, I am from Italy…

If printing this spool holder with supports, like Giampo suggested, doesn’t work then you may want to go to the extent of printing the spool holder with the flat parts facing down and the curved part (peg) facing up. You will definitely need support structures to hold up the entire print, but it will make it easier for your printer to print the curved parts. We have also printed a spool holder in this orientation which we just described. After a couple of tries, the final print came out well, but we had to file down the supports a lot in some areas to get the spool holder to fit into the slot of our printer. It looks like Giampo’s suggestion for printing your spool holder will work well, and this will increase the number of supports you will have to break off so you should only do this if your printer continues having problems on curved sections. Good luck!

Hi,
based on the attached pictures, it definitely looks like, way too high hot end temperature. I saw you wrote, you tried changing temperature, but still I would advice you to go even more down.
Additionally, I dont know which slicer you use, but if you can specify minimum layer time, go for it. 20-30 seconds might be neccessary, in case of small details.
Third thing is additional cooling. Usually, the root cause of this kind of curling up, is that the printed part does not have enough time to cool down.
Cheers
