I have spent many hours creating a fully functional mechanical Grandfather Clock. Having made a laserply version last year, I used the same plan heavily modifying every part to make it 3D printable and even better functioning. The clock is completely designed by me, but credit is due to the original creator who uploaded the plans online for free. I have heavily modified the whole clock and redesigned nearly every part but have kept the assembly instructions and basic gear structure the same with alterations to the gears to allow them to mesh better. I have spent close to 30 man hours making this clock and I intend to print it myself, though if anyone else beats me to it, please upload photos. I am very confident that it will work but I expect there might be a few alterations due which I will make once I have finished printing and assembling.
Attached are the original assembly files of the original creator. I have named all my parts the same for convenience and they fit together in the same way, but they are all slightly different shapes and sizes to help with 3D printing of the product.
For assistance on assembly feel free to ask
Individual parts are split for 3d printing because to complex to print in one go..but slot together and glue (advise tensol)
Now I have also developed a additional file which is an external driver plate so that the clock can be easily electronically controlled. The clock is designed with a hollow central shaft which a normal quartz driver can fit into and be used to turn the whole clock.
The frame I have included but I would advise just due to the size of the print, that you make out of a different material such as wood for strength and to save time. Also I have made it so it can be hooked onto a wall straight like shown in the render, because i thought it looked way better without a case!
Having based it off my own clock that I built and off the plans of the other clock I built, I am fairly certain it should work, the cogs are large but will fit in a 350mmx350mm printing base or slightly smaller but that's on the safe side.
There are a lot of parts and this is a huge project to print but totally worth it!
I have made the same scale version out of wood as is CAD and it works fine so the 3D printing version should also work fine, just have to make sure the shafts are correctly aligned and suitably oiled/fixed.
I hope you enjoy! Again, any builds would be extremely appreciated.
Also I made in Solidworks and therefore if anyone would prefer those files to make some alterations I am happy to oblige but on the condition that you send me your alterations so I can too update with these improvements.
