I haven't had lighted candy canes for at least 20 years . That is about to change .
This year I will have pixel canes. here is the initial concept .
They are just over 1 meter in height .I will add dividers the segment the light .

That's wild that we both posted "3D Cane" type content today!

2026 may be the Year of the Lighted Cane lol

Looking forward to your project.
 
Here is a basic 1 meter tall and 40 mm diameter cane . It's a 7 part print and slicer ready - manifold pieces !
I haven't printed as I'm out of translucent filament currently . Below pics show fitment and press together connections.

Fitment verified ! Negligable post required, a few strings at low quality setting .

I'll post the cut away print if anyone requests .
 
I totally missed the files- thanks.

I just sliced via Bambu studio @ 20% infill and tree supports, and it only took 435g.

How did you do supports on the long curved section? Studio wants to put support inside the tube and that seems like it would be quite hard to remove. And I think that's too drastic of an overhang to go without?

I just used Cura to proof the .stls were manifold . That is a quick design basic cane. You could probably print the curves horizontal without issue .

do u want cut away .stls to see how it fits ?
 
So . I've settled on volumetric canes as my design . The white portion will glow/light .
Trying to avoid direct led light or dots of light .

I printed just a small piece of the large curved piece from the first files. It actually printed pretty well with no supports, but it broke free of the bed in the final layers. I don't think that would have happened with the full piece since it would be better supported and not rock back and forth like this one. In the meantime, I've restarted it with a brim.

The walls are pretty thick... thinner would pass more light and save material, but be harder to join the pieces together

I'm not sure I'm understanding your latest design.
 
Light pass through won't be a concern if using 20% , especially if using translucent filament.
Good Pex is translucent not white .
My cane design is edge light only !
 
I went ahead and printed the large curved section in white PETG (closest thing I have to a 'transparent' filament)

It's a chonky boi. This piece alone weighs more than 2 or 3 of my existing canes, lights included lol.

Did a quick test with some seed pixels, and although you can certainly see them in the dark, it reduces them far too much for my needs. I'm sure a true transparent filament would help with that.

FWIW, I wasn't able to get it to print in PETG without having supports underneath. That was printing it horizontally on its side: vertically would have certainly required support, and it was a lot more of it. I went with 10% infill which was sufficient for a successful print.

If my PEX project doesn't pan out I may have to look at something like this, but with much thinner walls. That would make joinery tricky but overall work better for what I'm thinking of.
 
Thank you for printing/testing this and giving feed back . I now know how to fix this .
I will re-create the 7 pieces individually as hollow shells with simple flanges at either end for joining .

This will make them much lighter and thinner.

Was the 40mm diameter to large ? I noticed you mentioned seed pixels in another thread .

For testing purposes I'll provide you a cutaway as it doesn't consume much time or filament .
 
40mm is about 1.5 inches.

The PEX I've been experimenting with has an OD of about .88 inches or 22mm. 40mm isn't out of the question for me but a little bigger than I was considering. 25mm (about an inch) might be the sweet spot.
 
Has anyone printed with the transparent filaments? I've always been curious if they provide a nice smooth transparent view or do they have a milky or bubbly appearance to them?

I've printed loads of things with it . I think it is great and probably the most pure .
