Open a model page on MakerWorld and you see two separate things: the model and the print profile. The model is geometry; the profile is a set of settings prepared to print it: layer height, infill, supports, material choice.
They can be uploaded by different people and are rated separately. That is where the confusion comes from.
Where rating happens
You rate from the Bambu Handy app after the print finishes. The app recognizes the finished print and brings up the rating screen on its own.
If you missed it, you can go back through Me → Ratings in the app. On the web there is a rating tab on the model page.
Rating only works if the print went out with that profile, over the cloud. Download the G-code and print from an SD card and the system has no way to tie the print to the model, so no rating option shows up.
Model rating, profile rating
One model can carry several profiles: a fast one at 0.2 mm, a detailed one at 0.12 mm, a multicolor one for AMS.
The model can be good and the profile bad, or the other way around. That was the main point in the forum thread: they need separate ratings, because a model printing badly may be the profile's fault rather than the model's.
Be careful which you are judging. Giving a model a low score because a profile spoiled the print is unfair to whoever drew it.
Choosing a profile
When a model page offers several, look at:
| What | Why |
|---|---|
| How many times printed | A profile printed often has been tested |
| Its rating | Stay away from low-rated profiles |
| Which printer it is for | It has to match your machine |
| Material | A PLA profile will not behave the same in PETG |
| Whether AMS is required | A multicolor profile will not run without one |
| Time and filament estimate | Does it match what you expect |
A profile adapts settings to your printer, but not every setting transfers. Your own calibration values (flow ratio, pressure advance) stay in your profile; a downloaded one does not overwrite them.
How much to trust ratings
One complaint does come up on the forum: that ratings can be manipulated and negative reviews taken down.
Practical approach: do not go by stars alone. Read the comments, particularly the ones reporting problems. How many times a profile has been printed is a more reliable signal than its star average.
Sharing your own profile
If you find settings that print a model well, you can upload them as a profile. Bambu Studio sends it straight to MakerWorld. If you would rather measure the settings yourself, Orca Slicer's calibration tools help.
Labeling the printer and material correctly matters; a mislabeled profile spoils someone else's print and comes back to you as a low rating.
Your account name appears next to the profile you upload; if it is still the auto-assigned number, take care of changing your account name before you share.
