Super Mario Super Star clock
Print 100% infill, colour as you like, i suggest you put it face down in case you have a PEI, makes a nice finish.
I used a cheap AE clock mechanism, you can use any other, however fill or widen the hole in the middle with the “add modifier” option in slicer.
I recommend a bigger layer height on the first layer to really make a nice squished first layer.
