Cogsworth Clock

Cogsworth Clock (Beauty and the Beast)

This is a 3D model of Cogsworth from the Disney version of Beauty and the Beast. The model has been cut into portions so it can easily fit onto a standard MK4S build plate.

ASSEMBLY

The base and body are printed separately. There are four holes in each mating face, allowing you to use small pins (or headless nails) for alignment while gluing.

I've also made the model hollow so a cheap quartz clock & pendulum mechanism can be fitted inside. These mechanisms are only a couple of dollars, run for months on a single AA battery and are quite robust (see the attached image). Search for "Quartz clock mechanism with pendulum" and you'll find them on all the usual online sites.

• Note: I had to cut the little bracket off the top of my mechanism with pliers so it would fit inside the case.

• Tip: If you can find one, try to get a mechanism with an extra-length shaft. This gives you more room when fitting the hands and allows you to secure it from the front with the supplied nut, rather than from within the case. Mine has a standard short shaft, and things were a little tight!

There is also a cover for the back with a couple of holes where you can glue in small magnets to keep it in place.

CLOCK HANDS & PENDULUM

I designed custom hands instead of using the metal ones that come with the mechanism, but the choice is yours! Because the hands print in just a few minutes, I recommend duplicating them in your slicer and printing one at 99%, one at 100%, and one at 101%. This way, you can find the perfect friction fit.

The pendulum will fit directly onto the mechanism, but they are easy to design if you'd prefer to make your own.

Note, if your little one cannot tell the time, another option would be to not fit the hands, and to paint the "hands" that are part of the face of the clock (have a close look and you'll see two hand on his face). This way, you've got the pendulum for some eye-catching movement, but you don't have the bother of fitting the hands and so on.

PRINT SETTINGS

I printed this in Prusament Galaxy Black PLA, standing vertically, using the PrusaSlicer 0.20mm Structural preset with 4 perimeters.

• Supports: Required. I used "Organic" supports, which look crazy while printing but break away cleanly.

• Brim/Skirt: None needed.

• Time: Mine took around 26 hours to print and came out really clean. I only had to do some minor hand sanding with 400-grit paper.

FINISHING

By using black filament, the inside of the body stayed nice and dark after painting the outside. Because this was for kids, I used a water-based primer, water-based acrylic colours, and a final water-based gloss spray coat. My painting isn't great, but for a first attempt, it's Ok.

SAFETY NOTE

This model is not suitable for very small children due to the small magnets and tiny parts (the hands and pendulum).

A NOTE ON THE ORIGINAL MODEL

Despite searching, I cannot find the original base model on CG Trader, so my sincerest apologies to the original creator. I did however pay for and buy the original model I started with; if I find the link, I will update the references here.

Because the original file was an STL, most of my editing was done by creating additional shapes in Shapr3D and subtracting them from the main body. As such, the internal geometry is a little rough. I highly recommend printing a quick, rough draft first to make sure everything works for your specific hardware before committing to the final print.

If you need a hand with anything, please let me know and I'll try to assist. Good luck!
