A pair of these can be printed and placed side-by-side.
If the lid is held by hand, you can just shake the box to mix things inside. Shift it a little, and the opening can be used to return the beads to the storage can without spilling them all over the place.
It prints well in ABS if cooling is turned completely off for the first 50-60 layers.
I'm sure it can be printed in PLA/PETG as well, but I haven't tried as I want to be able to dry desccant with the max 70C, and the temp is problematic for PETG and a complete non-starter for PLA.
SH-02 has hot air vents closer to the center (i.e. non-symmetrical from the standpoint of a single box), so there are fins inside the air intake cover to distribute things more evenly.
The author marked this model as their own original creation.
