About this 3D model

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 Link to 3D model 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 See the build video here: https://youtu.be/4sf1IgcnPfU See the prep video here: https://youtu.be/-9JLq1R6IqM They are a lot more links to the design and the prototype in the videos descriptions Link to instructions: Instructions and 3D view 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 Bearings4 X 605 ZZ (5 x 14 x 5 mm) ZZ have a steel flange, there is very little friction with one flange removed
