Thread: Adventures in case-making.

  1. #21
    Ok, going to be firing up this thread again soon.

    Dabbled in a filament extrusion 3d printer for prototyping, ok for fit on the wrist testing, but details are poor.

    Upgrading to a higher resolution UV resin printer, which should be precise enough to fit a movement properly, and make a 0.4mm - 0.8mm dial.

    Also picked up a couple cheap SW200 standard grades, and I'll go over the same dimensioning as the 7001 in a few days. The advantage of the SW200/2824 is the availability of taller hand heights for thicker dials. I'm eyeing HH6 which should allow for 1.4mm thick dials, in case the printer can't hack 0.4mm well.

    I think this new printer will handle the detail. Holy crap!

    5 hours and 7 minutes for this tiny thing though...

    So here's a rough sketch of what I will be trying to do.

    Dimensions are very approximate, and will be refined once I upload the SW200/2824 manufacturing documents, and go over them like I did with the 7001.

    So the plan is to show how to look at the manufacturing documents. Then some brief pics of my terrible 3d modelling based on the final specs from the manufacturing documents. Then 3d print on the low-res filament printer to check how it sits on the wrist (I tend to make them a bit to long and flat). Then update the model, and print it out on the high-res resin printer.

    After that, repeat with a dial.

    Might take a while to get through this though.

    Colours should be the same as the 7001, minus the small seconds and dial clearance, but adding the date window.

    On the hand heights, I'm considering using HH6 for a custom dial, but am also considering using standard HH2 and finding a stock dial and matching the case to it. Maybe both.

    Modelling next.

    And some pics from the earlier, not-so-successful case. Still close enough to try again. Was shooting for ~6mm, which meant cutting all the tolerances close, and maybe shouldn't have started with such an ambitious target. This 2824 build will be a little more conventional.

    Curious to see how things will turn out. Interesting thread, Dimman.

    Okay, so what is going on here? Using an archaic 3d modelling and animation program (Caligari Truspace) I've used the dimensions of the overall movement shape (25.6mm dia x 4.6mm) and hand stack to create a simple space occupying model. Then I've added the dial (one 28.5mm dia, and one 34.5mm dia both 0.4mm thick) sizes of two somewhat common off the shelf dials. Then above and below, with 0.4mm clearance are the crystals for the dial and display back in 0.8mm thick cylinders, both 0.5mm larger diameter than the dials. That's the lower stack. From there I modelled some shapes around those pieces as my size constraints, making some curvy proto-case shapes. Both are 8.7mm thick, the one designed around the large dial is 42mm dia, the one around the small dial is 40mm dia.

    Next up is lugs, crown tube, and the complicated part of making the inside cavity and caseback fit together.

    In the slicer for the filament printer. Went with conventional lugs with a bevel on one and fancy cow-hornish lugs for the other. Print estimates 10 hours. And these filament printers aren't 100% reliable, so don't hold your breath.

    Here we go:

    And already had some adhesion problems. Caught it early and reoriented the parts.

    Let me know if I'm subconsciously homaging anyone. (Yes I know Vacheron Constantin made cow-horns hot again recently, but these aren't exactly a traditional cornes-de-vache.)
