These are the STL files of the great Clock of TheGoofy.
I rotated some models for an easy print.


You have to choose the supports and preferences.
After i printed the clock (in a few weeks), i will add some tips and maybe supported models.

frame 2 prints off faulty iv tried it twice all other parts seem to be printing perfect

Does it work? And does it require any extra parts?

Comments deleted.

Could anyone write up a step by step direction for this?

I've updated my thing with more details and even added some instructions: http://www.thingiverse.com/thing:328569http://www.thingiverse.com/thi...

I can do it after i printed this.
At this moment i have some problems with my printer, so it can last some days.
You can also watch the video of TheGoofy. It is very helpful.

i have a question on the frame front piece, there appears to be a pin that prints that is not part of the frame, i can't tell what its function is, you can see it in the render in blender as well just to the left of the angled post. I have translated the file names in for your stl's into English, i can send you the zip if you like might make assembly easier for others.

There were some pins in blender which are for simulating the mechanism, i think.
I cutted them off and forgot that one.
You can ignore it.

I have printed out the parts and am in a the process of assembly. First off, thanks TheGoofy for an outstanding project. And to you ToScH for converting to STL.
Has anyone assembled one? I am working on the drum assembly. It appears in the video the drum assembly is much simpler in design than whats shown in the stl. or much of it was preassembled...

These files don't look quite like the clock shown in TheGoofy's video. In the video, a gear with spring ratchet tabs is shown being printed. This prevents the weight from unwinding via the crank mechanism. There is no ratchet mechanism shown here. Also, the video mentions and shows 5 screws holding the drum assembly together. These files only use 4. Did TheGoofy upload a different version of the clock? This version won't work since there is no ratchet mechanism to keep the weight from unwinding via the crank shaft.

100 Points for you! :-) I've added the missing piece as STL "Uhr_Trommel_Ratsche.stl" to my project: http://www.thingiverse.com/thing:328569/#fileshttp://www.thingiverse.com/thi.... It needs to be mounted to a similar location as the other piece that holds the chord of the weight. This ratchet will then prevent turning back the gear which is driven by the crank. Actually the "planetary-reel" version of my clock was initially working without this piece, because friction of the crank was high enough. Some months later friction magically decreased, and I had to print this additional ratchet.

Thanks for the fast solution! I added the part to my remix.

Thanks! I was playing around in Solidworks, and made a ratchet that fit in the exact same place to fix the issue.

I have only uploaded the files which TheGoofy has offered.
Because i did not print it yet, i can´t verify if it works.
Maybe TheGoofy can answer this question...

"TheGoofy", This is great work. Just started printing it. Lots of parts but they all seem to go fairly quickly. Can you tell me what size pins to use and also what you filled your weight with. Thanks.

The faster moving the pieces, the thinner pin diameter. 1.5 mm for the balance wheel. Depending on printing quality I recommend to drill out to an accurate diameter. Minimal friction is important. I've printed with 0.125 mm thick layers, 30% infill. Balance wheel is 90% filled, and the wheight is filled with 1.2 kg nuts and bolts.

hahhaa im doing final assembly now :P

Brilliant, thanks for making STL's from TheGoofy's work!

Glad to see the STL files in 3d on the web :-) ... we should start a 3d-printing-challenge with the most complex and compact escapement mechanism!

I think you will win ;)
Did you have any tipps for printing it?
I will probably start in the next few days with it.
