The author remixed this model.
My printer's (Ender 3 S1 Pro) print bed was too small to print this flat, since the biggest piece has a dimension of 240mm while I have 220mm x 220mm print bed available. So I redesigned the biggest piece to be 215mm instead of 240mm. All other pieces are the same and everything fits together like in the original. The handle is still easily accessible when all 6 cans are in place.
