This is a mostly all 3D printed mechanical clock that will run over 24 hours on one rewind, run time can be doubled with a pulley
Link to instructions and 3D view
A 3D view can be downloded and opened in a browser, it is a Xhtml file
Some hardware is required, rods, screws, bearings, metal for the weigh
All parts are fairely easy to print in PLA on a 220/220 bed with a 0,4 nozzle, no support is needed, post processing is minimal with a decent print quality
While the assembly has no major challenges, it is still a delicate mechanical assembly that will take time and dedication to be sucessfull
Some parts will cover the whole bed: bed leveling and bed adehesion must be well understood
I have other simpler and free clocks if you want to try before commiting to this one
Expect to spend 2 or 3 weeks frome the start of printing to a finished ticking clock

Tools:
While a shop is not necessary, you need to have a way to cut the arbors and piano wire to size
A dremel tool with a cutting wheel can do
You need a few hand tools, pliers, screw driver, round and flat files, sand paper
Supplies:
5mm steel or brass rod
2mm piano wire
1 mm piano wire
Bearings
M3 screws and nuts
Glue, epoxy or super glue
String
Weight, steel balls, steel rod or other, between 2 and 3 Kg for straight drop
Shafts/Arbors
5mm rod
1 X 150 mm
2 X 106 mm
1 X 71 mm (lock rewind)
1 X 43 mm (anchor)
1 X 37 mm (maintain ratchet)
4 X 18 mm
2mm Rod (piano wire)
1 X 112 mm (middle gear)
1 X 93 mm (clutch to hands)
2 X 61 mm (clutch)
1 X 53 mm (escape wheel)
1 X 46 mm (anchor)
1 X 38 mm (hands)
1mm piano wire
1X 115 mm
M3 Screws and nuts
6 nuts
2 X 20 mm
3 X 15 mm
1 X 10 mm
Bearings
4 X 605 ZZ (5 x 14 x 5 mm) ZZ have a steel flange, there is very little friction with one flange removed
You will need a printer with a bed that accept a 202 /202 mm part (front frame)
You are capable of printing big parts with good bed adhesion from one corner of the bed all the way to the opposite corner.
While none of the parts are challenging to print, gears and the escapement need to be of adequate quality
You know how to set up custom settings in the slicer for optimal results
I use Esun PLA+ on glass bed, at 215 C and 60 C for the bed on an Ender 3
PLA or other material can be used

Horloge 24 heures de Jacques Favre. Bien suivre les instructions de Jacques et tout ira bien. Après plusieurs essais je suis à 1mm d’avance sur 12h J’ai personnalisé le cadran avec une de ses autres horloges. Très beau travail de Jacques...... Jean Claude
