Description

This is my 1:1 scale replica of PIXAR's own iconic mascot. It is exactly on model, with reference from PIXAR's own digital data and is built accordingly to the short Luxo Jr.

His bulb is vacuum formed polystyrene and he is lit by 4 super brite LEDS and powered by one CR2032 battery.



I got the files from Jon @ google sketchup and after splitting up the entire components, converting everything to .STL, I had it 3D printed at Tech Shop.

Instructions

I posted an instructable for those interested in a more in depth guide: instructables.com/id/Luxo-Jr-Revisited/

Head attaches to two neck joints, which then attach to the neck rods. The rod with the pegs at the very end are on top, while the pegs with the one in the middle are on the bottom. These attach to the hip joints, which then attach to the H-Rod and Leg piece. These two pieces attach to the waist joint which then attach to the base.

Small springs I got from OSH attach the hip joint to the neck joints and from the H-Rod to the Waist Joint.

UPDATE: I have now uploaded the STL file for the lightbulb for 3D printing. However, to get the glossy finish on mine, I instead used a vacuum former.

You have to tell me where you got the ball. :P

This doesn't appear to be very printer friendly. A number of the parts require manual rotation and possibly support. What kind of printer was this printed on?

I printed this using an Objet printer and an UP PP3DP printer, but honestly it should be no different for a Maker Bot. Just use your printer's "Automatic Placement" setting to get the required rotation for printing.

Due to popular demand, I have decided to include the .STL file for the light bulb. Enjoy!

Oh, this is so on my build list now. Hopefully I'll get it to print, I don't see anything too horribly challenging (but now that I said that, I'll be borked).

Great work sir! There is something about it that is cute at any scale, I've been to PIXAR and saw the enormous one out front, about 25Ft high. Still cute.

Will try a PLA bulb if you upload the file.

You've BEEN to PIXAR? I am insanely jealous.

Just plain awesome !

Oh this is OUTSTANDING. Can't wait to see the MakerBot Animators out there in the world tackle this. Heck, I have Dragonframe Stop Motion... gotta get printing.

Natural PLA is very nearly clear. And I've gotten good light through even ABS if I print it only one perimeter. You should include the bulb anyway, as it doesn't have to "light" to be awesome.

Well done.

Mattraptions on July 17, 2012 said:

Thanks! And once I find my USB drive, I will definitely include the lightbulb

Very cute! Now time for some stop motion animation?

Haha, indeed! Perhaps I'll create some kind of rigging system to simulate his "hopping".
