Designing a holder for the Carbide 3D pendant

Eventually, I’d like to work up a steel plate as a base for a platform which all the machine controls rest on on the swing monitor arm affixed to the table my SO5 Pro is on, but until that time, a space to hang the Carbide 3D pendant is wanted — since the front plate has two holes in it, and bolts for securing it, using them as an attachment point seems an expedient option.

Since this will be a 3D object, and I have failed miserably at actually using every 3D CAD tool I’ve ever used, we will rough this out in BlockSCAD, starting as usual with some measured dimensions:

which are then used for modeling features:

adding variables as needed:

and using them to build the dimensions incrementally:

Adjusting a bit we arrive at:

which needs to have the holes extended through…

Which is easily done:

but then raises the matter of countersinking the hardware/duplicating the original recess…

adding another variable:

this is easily done by adding the sockets with the adjustment to the elements which are difference()d:

Next, we model the “hook” itself as a module, piercing it through the plate and adding an additional plate which will also be removed so that the two parts will nest/mate.

First, variables to adjust:

and a module:

which needs to be instantiated with and without an offset.

The hook is:

which possibly wants something at the end to hold things in place.

The file is at:

and may be exported to an STL.

Make that was at. Apparently the contents of the modules were not saved for some reason — recreating now.

Fixed, now at:

https://www.blockscad3d.com/community/projects/2055323

making a test print now, and if that pans out will walk through exporting individual parts to cut and upload the STL.

After a bit of adjustment, I believe I have a good design for an SO5 Pro:

C3D Pendant Hook.stl (69.0 KB)

The parametric interface for BlockSCAD allows one to adjust the gap and part variables so as to increase the spacing:

and output individual elements:

as desired — I believe it would work well if printed in multiple pieces and then assembled, or if the individual parts were cut from suitable materials.

A further improvement would be to arc the sides of the hook to match the interior of the hanging recess on the pendant…

The above file works, but seems to require a bit of adjustment w/ a file or plane:

It’s hanging a little canted due to the USB cable being pulled off to one side — should’ve adjusted that. Further, note that in addition to 3D printing a modified shell I inserted a couple of layers of orange film in-between the “LO” light pipe and the LED.

Note that you’ll need two slightly longer M5 bolts, which raises an interesting question — if you replaced the stainless machine screws on the pendant w/ steel, could you then have a plate w/ 6 magnets which would secure it? (as opposed to opening the pendant up and installing magnets in the recesses)

This suggests a slightly different approach — extending the end of the hook so that it can just be filed to match.

One benefit to this design is that it offers a bit of protection to the BitZero connector…

Making a slight adjustment:

Printing now.

Success (after a couple of passes w/ a hand plane and a few swipes w/ a file)

Next up, printing multiple parts w/ different filaments (after further adjusting the end to match the internal rounding), then try manufacture in multiple parts using different materials.

Since Winston published his design for a holder:

the most expedient thing to do is to make use of that for the hangy part…

Opening it in a slicer we are able to export an STL

which then can be imported:

I got my pendant hooked up .

@jtclose :smile: I had mine on a small re-bent steel angle bracket (to avoid the point-loading that your wire is producing–what can I say, I’m a mechanical engineer :roll_eyes:) until I printed Winston’s bracket yesterday.

The file above wants a slim M6 nut — since I didn’t have any at hand, I just pounded in some nylon nuts:

screwed in nylon screws which were just a bit too long, then cut it all off even. Installing now.

That might be the best yet- I think we need to add a single drywall screw to the store.

I just finished installing my new 5.1 cross bars, repositioning the gantry forward, and installing my new printed keyboard, USB expander port and pendant mounts.

Everyone over here with their new 5.1 setups and pendant holders and I’m just cheering along my 4. I don’t even have a drywall screw yet. :sweat_smile:
