1:32 just so happens to be the most common slot car scale. RC10 slot car anyone? :)

Lookin' good!

I don't think a straight printed piece will hold up, even with the lattice. Nylon will do beter than fragile ABS, but I still think the rigors of actual use will tear it apart in short order. However, introduce some aluminum braces and reinforcements in the right places,n I think you'll have a winner.

My thoughts:

-Make the tub a little thicker, and create a recess on the underside to accept a 2" wide strip of aluminum, perhaps 2mm thick. This would essentially be a frame that the tub rides on.

-Your arm mounts; they will need to be seriously heavier on the ends to avoid breaking out.

-the arms themselves are going to be troublesome; if possible, might print them with a cavity through which to insert some music wire fore and aft, perhaps 3/32" dia.

-Hub carriers/C-hubs/knuckles; if you intend to print these, I would design the arms in such a way that they can also be considerably thicker to the outside of the pin holes.

Just my $0.02, FWIW.

You know... that's almost perfect size to pilfer a micro t for parts for.

The transmission internals could be put into a stealth style case or a bulky 6 gear case, suspension hardware, axles, stock dogbones or 3 racing cv joints, 3 racing turnbuckles, shocks... I could see it done with a bit of elbow grease! :D

Just think, he could use the printer to create stealth cases that accept different internals. or print an adapter to put another to mount another tranny in it.

That's bloody brilliant - keep us posted :)

Thanks!

Look like a fun project. I guess you can keep the cad files so in future when the printers get better you can produce much smoother parts.

Thanks for the comments! I think for practical purposes, the rear section may have to be all aluminum (flat piece) with a printed motor guard that is screwed on. The front section may need some aluminum, or more creative plastic reinforcement as well. For the center section, I'm hoping the ribs and gussets do their job as is. I agree the the arm mounts will probably rip out, unless I print them in place. I have no plans to print arms or any other load parts at the moment, but it may be interesting to try at some point.

For now, I think I'm going to print all three parts as they are and just see what happens. Should be quite the learning experience :mrgreen: .

Absolutely! When I get this mostly figured out, I plan on releasing the 3D files so others can build on them if they like.

Check with Rod, he will know for sure. If it happens let me know. I am down for a few. The whole process is very intriguing to see.

I'm not a slot car expert, but I do know that 1:32 is a very common scale. However, I won't be selling any of the parts I'm making; it's just for fun/learning.

I hope to print the whole chassis next week some time...

No problem - send me a free 1:32 chassis and I'll make one up. ;-
