Here's a couple of pictures of my SB13 build.
I will start by saying the clock design and associated STL files are fantastic....will done Steve! All the parts were printed w/o issue....the "no support required" is awesome.
The clock was printed with a Bambu X1 Carbon, the files were sliced and printed from inside the Bambu environment using the recommended setting, all the parts printed perfectly. I used Polymaker PolyTerra PLA for the major parts, for the gears I used Inland (Microcenter) Gold\Gray silk PLA. I believe PolyMaker and/or eSUN makes filament for Microcenter.
I had a couple of friction issues that required some attention, but after a couple of tweaks, the clock has been running for about 48hrs w/o issue.
Quick update: The clock has been running perfect for the last 5days.....beautifully designed clock.
I am slowly tweaking the pendulum to sneak up on the accuracy, The clock is currently running within a minute over a 24 HR period.
I found the ratchet assembly to be a bit sticky when winding so I used a very small amount white lithium grease on the face where the ratchet fingers make contact....this made it much smoother to wind. When using grease on something like this "less is more".😉
