Description

Edit : Cartisky3D made a review of this model (without weights) on youtube

=> short and video

Hi,

Concept:

I designed a mechanical clock to better understand clock mechanism.

I could get this clock to run 42 s with a single rewind of the PLA spring.

It might run longer with other kind of filament.

Please let me know if you beat my record ;)

No hardware is needed but you will get a longer runtime if you weight with “InertiaWheel” with some M4 bolts.

I know my design can be improved and I greatly encourage remixes.

You can find my source file on Onshape here.

Printing:

It is an easy print. I recommend using Arachnee to get the right spring thickness. I also recommend using 100% infill for the InertiaSpring to add some weight to it.

Assembly:

There is a quite a lot of parts (which makes the assembly satisfying) but assembly is straightforward based on the 2 exploded views below.

/!\ Make sure you insert the arm in the right orientation. The face of the arm should be parallel to the face of the escape whee:!\ l teeth.

/!\ Make sure you insert the ratchet in the right orientation

Well the print setup and quality is top notch. It's a fascinating design. But alas, I could not get it to work more than 5 "ticks" no matter what I tried. I did use the 4mm bolts. Tried multiple combinations of how many were used. It just will not continue. I'm bummed about that too because I was hoping it could be the basis for a cool project idea I have.

@SigmaT4

You have to add weight (inertia) to the top wheel to get more run time. Little M3 screws works fine

@FerrumCampitor

Replying to @SigmaT4 :

As I said, I did add the bolts. Didn't help. Any other advice? I'd love to get it working.

@SigmaT4

Replying to @FerrumCampitor :

@FerrumCampitor Oh yes you did, sorry. Two possibilities : you have too much friction (maybe the top wheel is rubbing against the chassis, or the chassis is squeezed too much by the top gear assembly) or the spring is too soft.

I'm having trouble with the clockwork... It doesn't go full automatic... Too much pressure? Is there something that I'm missing?

@GyanZoe

learn from my experience, don't squeeze the push-ins too tight or they would jam

Replying to @GyanZoe :

Yeah I noticed... I leaved it like an ornament better... it was my first or second print on the bambulab... now its more like a trophy XD

this design works great! I have tried several escarpment mechanisms and this one was easy to put together and worked first time! printed great and needed no glue or sanding. I am very happy with the results and will add weight to make it go longer. Thank you for the file!

@webgrafix

It took me a few tries with different parts, but I was able to get it to work flawlessly!

A superb result considering everything that is possible with 3D printing. The spring opens in 17 seconds. It's probably due to the fact that it was printed on the P1P and automatically upscaled, which makes the spring less dense.

Awesome job. I have been printing all the clockworks I can find and highly prefer fully 3D printed models so this piqued my interest! Update: Got 17 seconds of movement with no weights, posting video this week
