This frame is made to follow the 2 mm thick dial and completely cover the walls of the dial opening.
If you decide that the appearance of your clock needs to be improved, if you had an accident while printing and the layers shifted (for example, due to a power outage), or if you ran out of filament and the transition between colors looks ugly, here is the perfect rescue.
Model is supportless. It is very easy to print.
Don't forget to degrease the print bed thoroughly.
The assembly itself takes no more than one minute.
The entire frame is in one piece. If the printer is properly adjusted, it can just snap together and no glue is needed. Otherwise, you can just secure it with glue or double-sided tape.
The author remixed this model.
The frame is 10 mm thick now. It cowers the walls of dials opening completely now.
