MakerBot Clock
Description
The pendulum swings, releasing the escapement. Stored energy is transmitted through the gears. The hands move forward.
Tick...
The pendulum returns, the mechanism shifts. The clock moves, a physical manifestation of the passage of time.
Tick...
The modern world is regulated by this simple sound. A sound reaching back to the first mechanical clocks in the 13th century.
Tick...
Each tick is uniquely human. It expresses a yearning to bring order to the chaotic passage of events. An attempt to break the unfathomable eons into moments small enough to be understood.
Tick...
Tick...
Tick...
Created by Thingiverse user Skimbal, designer of the Turtle Shell Racers, MakerBot Botmobile and the Gothic Cathedral Playset.

Kits aren't available any more apparently.
Aside from the wood frame pieces, you can pretty much get the hardware needed from a regular (metric) hardware store. It's mostly screws and nuts. The bearings I used are 623ZZ from vxb.com. They are 3mm ID X 10mm OD X 4mm wide. The list of kit parts is found on the assembly page http://www.makerbot.com/projec...
(Oh, and I recommend going through the assembly instructions carefully to figure out what hardware is needed. For example, if you don't have the lasercut wood pieces, you don't need all 17 of the M3 screws and nuts to put them together...)
Was an excellent workout for the Replicator. I did a little mod to the second hand and am planning some more. Have been experimenting with an improvement to the winding drum. All will be posted.
I have found an issue with the Middle Frames, both parts are not on the same plane, can someone fix this and upload a new STL?
found a video of it in action

Looks like a really nice clock but Makers need to be aware it will not print on a ToM without scaling or modifications. This project appears to be optimized for the Replicator. I wish I'd known that before dropping the 50 bones for the hardware kit. :(
I'm making progress hacking the larger parts up for printing on the ToM. The back frame has been printed in three pieces. I have two of the three front frame pieces printed. The hour wheel is ready for printing and the minute and second hands are broken down but still need cleanup in Netfab.
For those who are thinking of building this clock but are unhappy with the Makerbot price for the hardware, realize the fishing rod reel bearings are the reason for the high price. I looked around on the net and could not find any for much below the $50.00 Makerbot is charging for the hardware ki
t. I'm sure Makerbot was able to source the bearings cheaper than the sites I was looking at but with seven bearings in the hardware package, $50.00 starts to look like a fairly decent price.
Making progress ToMifying the clock design. I now have the bottom frame printed in three ToM sized sections. I'll keep going and post a derivitive if there is interest. 8-)
On clocks it's customary to use IIII instead of IV for 4. I'm not sure why.
Wikipedia actually has a discussion about it, though, http://en.wikipedia.org/wiki/R...
From you write it sounds like you read Terry Pratchet's Time theif. Tock

Is it just me or do these gear ratios not add up to seconds, minutes, and hours?
