This is my design of a sandclock using the software HUEFORGE. Perfect for a gift or decor your room. This file is suitable for all printers (not only bambu). in case you don´t own a Bambu, just take care of the layers height in order to make de filament change.

Please print at 0.08 layer height. The file also includes the .amf with all the color changes but also here you have the note:

Swap Instructions (Just in case you want to make the filament changes manual):

Start with Black (xyzfilaments)
At layer #5 (0.52mm) swap to Dark Gray (xyzfilaments)
At layer #9 (0.84mm) swap to Light Gray (xyzfilaments)
At layer #14 (1.16mm) swap to White (xyzfilaments) for the rest.
