Lightcycle Model Kit by cbabbage May 11, 2012

Featured Thing!


I originally created this 3d file about 12 years ago for an old PC game project called GL_Tron. When I received my Thing-O-Matic last summer, this model kit is one of the first projects I thought about creating. After many hours modifing the original model it's finally it's done!

EDIT: I have now included individual part files per request.

Have you tried enabling support and setting the overhang threshold to something near 90
°? The support should stabilize your print. I think you can increase the support spacing for that purpose, but I never even made a print with support yet, so I don't know what I'm talking about here ;)

Also, you can import the stl into a CAD program (I would use openSCAD, but it's entirely up to y
ou) and turn it around or add your own support however you want ;)

I use Slic3r. Either the piece will bend over a little after 2/3 which means the rest will be out of sync, or it will fall over completely while printing in thin air :-(

I have ruined 8 of them already.

AWESOME! I just uploaded an MCP model @ http://www.thingiverse.com/thi... and after adding the Tron tag found your Light Cycle; man, very very nice!

Tron on baby!

I have included an illustrated instruction manual to help guide you in assembling this kit, but here are few notes to help get you started.

All of these parts have printed very successfully for me without rafts or support. The one place on the front wheel that needs support, has it built into the STL file. After printing you just trim off the small support wall.

This kit also uses 3mm pins to align parts. Because I am still printing with 3mm filament, I just cut short 6mm long sections to use as pins. If you have a Replicator, or print with 1.75mm filament, I have provided a file to print a set of pins.

The parts for this model are separated into groups by color to replicate the design of the movie Lightcycle. The frame and wheel hubs should be gray, the windows and wheel covers black, and the wheels and body another color like blue or red for example. Of course, there are no rules.

This is difficult for me,

I can not get the top window right. It becomes to hot at the end.

Even printing 6 the same, to allow the filament to cool does fail, as they tip over.....

Would you consider publishing it on its side?

What software are you using to generate your Gcode? In RepG you can just rotate the part to the orientation you want to print with. Also, if your having trouble with it staying stuck to your platform, try printing with raft and support.

How about one more piece? A 0.1 - 0.2 mm light trail to attach on the back wheel? Must go fire up blender...

Awesome! This might be a good application for the new glow in the dark filiment.

cbabbage on May 30, 2012 said:

I know! I tried to print one in glow-in-the-dark, but I could not get that stuff to run through my TOM. It would just slip and clog up the spurs of the drive wheel. I want a glow one too!

Awesome!!! I used to have this toy as a kid, it used one of those zip chords to wind up the wheels that had a flywheel, then you'd set it down and watch it go. The whole thing opened up like a hinge so you could put little men in it. I think we stuffed our playmobile guys in there and watched them race.

I love to see all the different color combinations!

jamesglanville on May 17, 2012 said:

awesome, I ran out of cream pla while printing the body so I used the pink, but still looks cool :)

That's really great, good use of the UV red. So much like the original color! 8-)

Really Great model, thanks for posting it up, I had a lot of fun printing and building them.

I had no super-glue to hand so I made them up by melting all the ends of the fixing pegs with a lighter, as you assemble each part it all sticks together, the windows are held on with double-sided tape, all the other parts just uses the melted pegs method.

Thanks again.

Nice! I use Plastruct Bondene Styrene
amp; ABS cement for most all of my ABS gluing. I do sometimes uses just Acetone with ABS disolved in it too. Never thought of just using a lighter:)

InfiniTTTy on May 14, 2012 said:

It just so happens I have all of these colors! Time to start printing!

Yes I'm old. Old enough to remember when the MCP was just a chess program!

cbabbage on May 13, 2012 said:

I never wrote down the scale on the instructions! It is about 1:20th scale, or 500,000,000:1 depending on what world your referencing :-D

my only regret is that i can only "like" this thing once. thank you!

I spent hours playing GL_ Tron with my friends :-D

I have put this project on my blog: http://www.3dfuture.com.au/201... Great Effort cbabbage!

Busybotz on May 12, 2012 said:

Impressive! You have raised the bar 8-)

My kids will love it. I have the red and black filament, for the silver parts I will use either yellow or blue.

Busybotz on May 14, 2012 said:

What fun. I printed 2 and a 3rd is in progress. Everything fit nicely, except the printed pins are too short, they were quick to disappear into the holes. I wish I had measured them, but the prints left my hands while they were still warm :-D

Amazing effort by cbabbage. If you have idle bot time, give this a look.

I will post photos later, when I find where my son stashed his new treasure.

Good lord, you made an assembly PDF?? You've gone above and beyond.

cbabbage on May 12, 2012 said:

The instructions might be overboard, but I wanted them to feel like they were from a classic AMT model kit :)

absolutly brilliant! :)

Roboteernat on May 11, 2012 said:

nice! im off to order some grey/silver PLA!

cbabbage on May 11, 2012 said:

I ordered some too, but it will not be here untill next week, so on the cycle in the photo I used a silver Sharpie :)
