The "lightbulb" is a 5-sided spiral that forms the general shape of a lightbulb. I made this a few years ago as a test piece and I've updated it just for you.

I've included two sizes:

Full size: about 4.8 inches tall
Half size: about 2.4 inches tall (...yep, that's half...check!)

I've also included each STL file in two resolutions.


I was able to print this without support on a Rap Man. The only tricky part is the merge at the top. It is fascinating to watch the arms be built up, especially when they are just about to be connected. More recently I printed it with my new UP! printer, but wasn't able to completely disable supports, and it was a real job getting the support structure out. Don't print with supports unless you have to.

As Schorhr said, and perhaps others, these would make some lovely earrings when scaled down... :)

Printed this in one perfect pass with Slic3r (well, nearly perfect) tonight. That's AFTER a week of tweaking SF43, SFACT up and down all over the place and never being able to print anything more than a goopy mess once it hit halfway up. It blew my mind.

MakerGear Mosaic .2mm layer, 1.75 PLA

It looks fabulous. I'd say you have it tuned pretty well.

That's the beauty of it; you don't really have to tune much of anything!

Just did a full-size one on my height-extended Cupcake. Still only a MK4, so I'll be giving some acetone a shot later on to smooth it out.

I printed a half size on my Cupcake, it is very, very stringy but it was able to complete without failure.

Did you ever figure out what settings to use to print without supports on the Up!?

I have not. I don't think it's possible. I'm going to ask for the option in the next software update.

I have not printed it as an earring, but I was able to print the LightBulb HalfSize.STL (1:1) without support. The top gets a litte rough though.

I used

V 1.15

.2mm Z Resolution (and Baseheight)

Part Angle
°, Surface 3 Layers
Support dense 3 Layers, Space 12 Lines, Area 20mm2
Print unsolid model checked

Just a random setting from an other complex print. I don't mind cleaning the support if the surface gets smoother, I might print another one.

Printed mine at 29mm/s 20% fill with ABS and no supports. Came out really well on my MB TOM Mk6. Interesting texture I got due to the filaments being fairly wobbly
amp; my need for speed.

Thanks for the design! 8-)

i ran at 55mm/s,10% fill (not that fill is relevant on the thin features). looks like crap, a perhaps a tad too hot, but decent! 29 is just crawlin along man!

Makes an excellent door bumper when printed 1/2 scale in PLA. Quite springy.

Great design!

It printed with no support on my TOM. A few little filament strands here and there, but all in all, I was very impressed.


Wonderful! I look forward to seeing it printed

Wow. Nice shape. I am so going to print this as another earring for my fiance
é :-) Keep up the good work!

Wonderful! I look forward to seeing it printed

I will upload a picture as soon as I can get to it :-) It might take a while though.

This is one of the many reasons why I want a 3d printer, by any chance would you be selling these?

I'm not selling them, but I imagine you could have one made on Shapeways or some other web-based rapid prototype-er...or find yourself a friend with a RepRap and have him/her build you all the parts for your Rep Rap!

So, Im thinking about getting the new TOM. Would anyone mind giving me some feedback on the quality of the prints? and maybe some pics? (i know I can find some if I look, but theres no shame in asking!
