I like the well-known brass movement holder for doing work, but when I have a movement in the "waiting for parts" mode, it is nice to have it sitting in a nice stable holder.  So, I decided to print this movement holder.

Print time was 20 minutes.  Probably took me about that long to design it.  Now that I have one complete, I can tweak it for other movement sizes with only a few minutes of effort.

FYI, this is a Landeron 51 chrono.  I cleaned it and it is running fine, but I need hands and a decision about the dial.  I have a dial, but it is in really poor shape.  I see hands and dials on Ebay, so I just have to decide which one to commit.

I just uploaded these movement holders to thingyverse as well as two types of movement rings for Seikos, all free to use,  modify and distribute. Just doing my bit to help fellow enthusiasts.: ht

This type of holder should be so sligly undersized so to grab thanks to a slit in the diameter. And when is for a chrono mov.t all the difference is made by having pushers.

Will you publish it on Thingiverse or perhaps just attach files here?

I am attaching the Freecad file.  I use Freecad which is open-source software that is heavily supported and it is FREE.  Been using it for three years and love it.

 

STL file also attached, but it is not as useful because it is much harder to edit.

When I get some time, I will parameterize this for easier mods.

My son owns the printer, I just feed him the drawings and he works his magic. I'll see if I can get any advice from him and pass it along.

Thanks!

I use a Lulzbot Mini which I bought about five years ago.  Have been very happy with it. Print ALL the time.  It is a little pricey.  I suggest you consider a Prusa.  The product line is well received and is very economical.

Good work on the holders, I am printing the 2 for 1 now.

Hope you like them 🙂

Anyone have any 3D stuff they have made that would be good to share, I asked on another post about movement holder rings for Seiko (not dial spacers) but nobody has responded

Sorry I don't have a separate file for each holder, I sketched them out and my son drafted them for his printer. I have now forced myself to learn the software he uses, but these were done before that. I'll see if I can get him to split them out.

Here is an update on the movement holder.  When I store an unfinished movement in the popular domed parts carrier, it tends to flop around if I try to place it in the center.  The solution was to put a base on the holder that sits nicely in the center partition.

I have a 3D printer on the way and am playing around learning FreeCAD. This looks similar to what I will be trying for my first project (movement holder that fits in the hand setting tool). Could you post the FreeCAD file? I'd like to see if I can adapt it to what I am trying to do.

 

By the way, your movement holder has that 'ledge' that is below the top of the holder which the movement rests on when in the holder. When you designed how thick the ledge is and how far down from the top it is, did you get those numbers from measurements you did on the movement or is there some other way you decided on those numbers?

WRT does not support FreeCAD file types.  PM me and I will attach to my reponse (if it lets me), or we will go offline via email.

My design was a simple hack more or less.  All measurements except for the width of the movement were SWAGs.  You will see in the FC file, I created a spreadsheet to parameterize the elements.  The extra piece on the bottom to fit the movement holder was also an "addon" hack using the Part workbench.  It too is a hack...lol.  When exporting to stl, you have to select two sets of elements.  If I were to do it over again, I would assemble the whole thing using Part Design workbench.

Wow, great minds think alike, I use freeCAD and also have a 3D printer being delivered by Santa 🎅, I currently have to bribe my son to use his. I was was thinking on Friday afternoon that it may be cool to try some parametric modelling in freeCAD and sketched out a parametric movement holder. My idea was to measure the movement outer diameter and then let freeCAD spit out the complete design.

Here is what I sketched in my lunch hour (including a doodle I did whilst on a very boring conference call) on Friday:

holdersketch2.jpg.6143123ae8885119aa056be816cb26ed.jpg

I also plan to put a fillet (0.25?) on some of the outer 'corners' mainly for aesthetics, and one on the entry to the seat to make it easier to get the movement in, but didn't get time to add them to my sketch, blue circles above.

 

Also l1  is the cutout for the stem/crown, was thinking of making it U shaped rather than square, but would model it as a square and simply fillet the corners to make it a U shape.

Just in case you can't make out my handwriting:

d1 = variable (the movement holder OD and the only input you need to make)

d2 = d1 + 10 mm

d3 = d1 - 5 mm

d4 = d2 x 1.5

r1 = h2

l1 = 10mm (with 2mm filets{?} to make it a U shape)

h1 = 5mm

h2 = 30mm

h3 = 5mm (will only need this outer dimension also to be h3 if I decide to keep the 'shoulders' at the top of the model, thinking I may just skip the outer shoulders and have the top and bottom linked by an ark without the shoulders... I will need to think about this....any ideas??? My initial thinking is that the shoulders may flex a little as you push the movement in and grip the movement better, but not sure how realistic this idea is?) - see version 1 and version 2 below.

Once I get to grips with it, I'll post the freeCAD design on thingiverse and you can also PM me for it from here 🙂

Think I did it.....

Below  is my parametric movement holder (size 30mm movement)

image.thumb.png.4529885b22908c632f494e64018ad422.png

Below is size 10 mm movement (minimum size before model breaks):

Below is size 70 mm movement (maximum size before model breaks):

And here is the Parameters table - only need to change the red text cell at the top:

PM me if you want the link to download 🙂

This is in FreeCAD not sure if it will play nice if exporting in other formats, but I'll give it a go if you let me know what you need.

I think I managed to create a link you can download the freeCAD file:

      Is this a 'hack' ?

      By oldhippy · Posted

      I need to see photos of the whole movement before I comment.

      Omega cal. 565 - low amplitude

      By swiss2k · Posted

      Hi @Jon, so, from one extreme to another the beat error is 0.1(min.pos) to 0.2(msx.pos), and as you mentioned the rate does up and down dramatically. Also checked the position of the collet, and the collet is not central to the jewel on the balance cock. Balance moves freely, per my understanding.   So, after 24h the ampl. fell down by approx 20 deg, which I would assume is expected. After adjusting the endshake I believe I gained around +10 deg. of balance movement. Which is great, and overall the balance is not at 220'ish deg.   What I did next, some might think is non-orthodox, but was wort a try. I too the mainspring out, checked again for endshake and if the pin moves freely, and cleaned everything. Usually when installing the mainspring I would use some barrel grease on the barrel walls, install the spring and put a 2-3 drops of D-5 oil on top of the wounded spring and in the places where the arbor sits. This time I took the spring and applied a ultra this coat of Molykote Dx paste on the whole spring, before installing it in to the barrel, and added some oil to the arbor as usual.  The result improved, at a full wound the balance produces about 230-237 deg. @JohnR725 I'm getting closer to 300 😃   What I am noticing, there is a fluctuation in amplitude. With time it would rise and drop about total 8-10 deg in an interval about 2 minutes. I assumed this ruled out the power transfer from the barrel itself. So I took the gear train out, cleaned and lubed.

      Balance spring fell out of regulator pin.

      Thank you so much, Hector and CJ. I appreciate the tech sheet and the video. Gasp, I think I will make the attempt. What's the worst that can happen? I think there may be a new balance complete in my future, though.  I'll update the post and let you know the result. R, Frank

      Movement holder made with 3D printer

      By Waggy · Posted

      So here is the new base (v 2.1), I made it so that the base will fit over and swallow the stump of the hand pusher tool (or at least my clone of the tool), I also reduced the OD of the bottom skirt a little as it looked/felt a little large, here are a few pictures and the fake .pdf file which you need to convert to .zip once downloaded.   The cut-out seen on the below image on the bottom of the base should swallow the OD (40 mm, +0.1 mm tolerance) of the stump and the height of the stump 9.5mm (measured to 9.1mm, but rounded to 9.5mm) - let me know if this works for your tool.   Note, I think you may need to print supports for the new internal shelf created? Here is the fake .pdf for just the FreeCAD base file and 3mf files Modular Movement Holder.pdf Here is the fake pdf for complete set of the new base and ring FreeCAD/3mf files: Modular Movement Holder base and ring v 2.1.pdf However, I'm wondering how often you could use this feature, adding the dial usually increases the OD of the movement, so you would need a new (larger) adapter ring tuned to the OD of the dial and I wouldn't like to grip the dial in any kind of movement holder if It could be avoided for fear of damaging it. Maybe I'm misunderstanding you?

      By HectorLooi · Posted

      Hi Frank, you have dived headlong into the deep end. Hairspring work has to be the scariest thing a newbie has to tackle. Your hairspring appears to be bent and just putting it back into the regulator would not allow the balance to work properly. It might start oscillating but the performance would not be good. The proper thing to do is to unstud the hairspring, remove the hairspring from the balance, reinstall the hairspring on the stud carrier, reshape the endcurve and centre the collet to the balance jewel hole. This challenge would either make you or break you. Hope that you will be able to fix your watch. Welcome to the world of watchmaking.  Watch this video. It think it'll give you an idea of the task ahead. From your 1st photo, I think you have a etachron type stud. Let me see if I can find a video on how to remove it from the arm.
