Printed in 2 colours, black and white, the shade of grey will depend on the transparency of your white filament, there is 1 layer of white over black to create grey.
First layer is printed very slowly to ensure adhesion of the black outline, you may be able to speed that up if you have good first layer adhesion.
The hook/loop is a separate object with this model, so you can scale up the x and y and keep the hook/loop the same size, do not scale the z axis, or you can remove the hook/loop completely and print as a fridge magnet.
The mouth parts can be switched to red filament, but it is really not worth it at this scale.
I have included a file in the raw files section to use if you want to use grey (or any other colour) instead of white over black for the fur
