Update: Now includes a smaller variation for the A1 mini.

A perfect addition to keep an eye of the time while watching prints. I have a wall clock near my printers and decide to see if I could create coordinate with my printing space. This clock is the same size as Bambu's reusable spool and features a customizable label and faux filament.

For the clock mechanism, I used a common quartz movement with a shaft long enough to fit the 3.5mm faceplate. These movements and hand assortments are quite cheap on sites like Amazon (example). I settled for simple hour and minute hands that are 55mm and 90mm respectively. The Bambu Lab Clock Components Kit 011 also works well, but with shorter hands.

The spool, text, hour marks and center hub cover are all separate objects making color adjustment easy. While the text can be changed, I've found Bambu Studio's text tool is finicky so be careful (and patient).

The filament ring can be printed in your favorite color and material but is entirely optional. If the fit is too loose simply scale the part a bit or add a few drop of glue.

Please feel free to reach out if you have any problems, need adjustments or have suggestions!

Based on legacyofbob's nice hex remix of Bambu Lab's reusable spool.
