I designed a clock to look like a Cuckoo clock but with Australian animals. The various parts join together using 3D printed dowels and keys, no bolts or screws needed. It uses a clock mechanism I had in my junk box. The mechanism is 58mm x 58mm x16mm.
I haven't finished printing all the parts, but so far the pieces printed fit together nicely.
The only supports needed are on the face and I printed it with the numerals a different colour to the face.
How good are my drawing skills, can you name all the animals. :-)
