Glow Stick Candelabra Hollow Arm
Derived from
Description
I've tried printing this, and it seems to be hollow as designed, but I can't get the only wire I've got to go all the way around all the curves. Maybe someone else will have better wire, a better print, or a cunning plan, for making it work.
The hollow ends with a gap in the middle of the tab to attach to the main candelabra body - ideally, the wires should be able to rejoin the main body through that.
- UPDATE [5th September] -
Two newly updated versions - both with the split tab raised up to the half-way mark.
Version 07 has a ridge along the end of the tab as a support leg.
Version 08 changes the ridges to 'T' shaped, to avoid a printing island.
Instructions
I've got plans to attempt to stop the print before the hollow is sealed - and embed the wire in the channel to then be printed over - if you try this, please let me know in the comments!

I was able to get 4 wires of 30 gauge down the hole. I have added a 3 color rgb led. I have modded the base and the middle section to take 3 maybe 4 AAA batteries. One thing I noticed on this arm is that you moved the tab down so it prints better...but it puts the arm off center. You could do this http://www.flickr.com/photos/2... My hollow arm (which sucked) had that support for printing. It worked well and you just snip the support off before attaching. Could you modify this arm to center the two tabs and add the support at the end?
Ooh, clever. Yes, I had to move the tab down, because (now that it has a hole in the middle) it was warping and twisting without support.
I'll try your modification and see if that helps.
Also - I'm ever so jealous/impressed that you've got an RGB LED in there - you can have realistic candle flickering, brilliant steady white, or color cycling rainbows! What flexibility :D
Success!! I was able to get the 30 gauge wire wrap wire threaded on the first try. I will use that to pull though 2 more wires. Thanks again for making this hollow arm!
oooh I missed you posted this. I got mine to work http://www.flickr.com/photos/2... but it isn't very elegant. I am going to print yours and see if I can run the wire wrap wire I have from one end to the other. Maybe try using thread and compressed are to blow the thread through. Then use the thread to pull some wire through?
sticking the wire in the channel before the bridge layer should be easy enough and work fine.
will be easier if you make the channel a U shape rather than a circle so it's still wide enough at the top for you to drop your wire in before the bridge

I sent you a message with some links to some pictures of what I had in mind to put 4 batteries (AAA) and an arduino pro mini in this puppy. Let me know what you think.
