I printed this to repair our Prusa I3 MK3 that broke due to a BLOB MONSTER. You have to print it in PETG because it has a higher temperature resistance. Printing in PLA lead to a part that melts, I tried it by mistake. I had some trouble with the adhesion because they asked to add glue with PETG since it sticks too much on the bed. But when adding glue it would not stick at all. I did not put any glue and was able to remove the part without damage.
