Completed My 3D Printed PLA SO3 Drag Chain Brackets

Post by madhatter » Wed Aug 12, 2015 9:56 pm

Here are the pics of the final version of the brackets that were printed individually and installed on my SO3.

Here are the pics of the four brackets that were printed all at once.

Here are SolidWorks renders of the four brackets.

NEW EDIT as of 02OCT15: Here are the STL, IGS, STEP 203 and 3DXML files if anyone wants to take them out for a spin.

The numbers of each bracket are just the order in which I designed them - they do not have any other meaning. I started with what I thought was the easiest to design, and worked my way to the one I thought would be the most difficult to design.

I am using #8-32 flat head stainless steel machine screws to hold the drag chain to them. Some places where I can't put a nut, I reduced the hole size and have the screws threaded into the brackets, and there is plenty of holding power. Other places, I am using a #8 washer and acorn nut because I like how they look, and I know if I don't I'll end up hitting them with my arm and cutting myself on the exposed threads. I am using M5 or M6 (as appropriate) stainless steel screws, nuts and washers for holding the brackets to the machine because I picked up a bunch to have on hand for spares.

For those with 3D printers, I can share the STL files, and if anyone is interested in purchasing them, let me know. If there is enough interest, I'll put some up for sale.

Thanks for taking a look.

That looks great. I may add some chain to my S3 in the future.

Thanks. Take a look at whether my brackets and your limit switches can live together, and if not, take some pics and I'll see about re-designing the brackets to make them work together. I plan on adding limit switches to my SO eventually, so I might as well get them to play nicely.

I can't tell with 100% certainty from your photos, but I think there might be one area where they interfere. My kit includes two actuator parts that bolt onto the ends of the X-Axis. It looks like one of your brackets may interfere.

On the other hand, it would certainly be simple to just add that actuator extension to your bracket. :)

Let me know what 3D program you use and I can see if SolidWorks will save the brackets in that format so you can modify them. If you'd like.

Printed a set of the brackets in silver and they look great - at least I think so. I think they'll look great on the machine.

Looks like you are running the USB cable and the router power cable through the link. Are you having any problems with the software loosing connection with the SO3 when powering down the router? I am using the Carbide software and having this problem, separating the cables as much as possible helped a lot but I want a drag chain and want everything to look clean.

Also, I just received T. Foreman's limit/homing switch kit. Has it been confirmed if the brackets will work together?

Chains give the machines that 'Professional' look, and as they're cheap, it's well worth it.

It may be tempting to use different size chains on different areas, but don't do it.
With one size, it means that any parts leftover can be used as spares anywhere on the machine, and also that if one needs to be slightly longer, there's no problem adding leftovers to it.
(The chain going to the X-carriage on my SO needed to be slightly longer than 1m, but the one from the table and up to the Y motor mount could be shortened. So two lengths of 1m was more than enough. )

Yes, 2m was definitely more than enough. I am still debating whether I want to make brackets to run a chain from the Z-carriage to the router.

On one hand, the router power cable only touches the SO3 when the Z-carriage is all the way right and down.

On the other hand. It would look complete as far as the wiring goes... I guess I should get to designing the last set of brackets.

Finished installing my drag chain last night thanks to Madhatter for posting his brackets.
