3D printed tires are not ideal. I want a better solution

Found some cosplay EVA foam (86 KG/m2 in density), and that may do the job. This type of foam is generally easy to find in shop specialized into cosplay, but you can find it on amazon too. From what I can see having it in my hands, it could be suitable for foam rc tires, and you can get them is various range of density. One thing which is left to do is to find a way to cut donuts in 10mm thick pannel and then find a way to glue them (neoprene liquid glue should be perfect for this).

First cutting attempt was made on the laser cutter at the fablab... Due to laser focusing and the difficulty to get the foam flat (which is delivered in rolls), it's far from perfect. I'll have to try in CNC, but in the meantime I'm exploring ways to work this out with simple 9mm cutter blades with 30°angle and 3D printed part.
Printed part and blades mount

A jig to position the holes

Next the base and something to retain the foam are in place

And gere is the result:


Conclusion : more work needed!  The blades are too flexible and too fragile. One of them broke. And if the positionning of the foam is not perfectly seated, it gives unapropriate results...

Side note for Flo : this should work as well to do some Coors onroad tires when I succeed to find a way
Side note for Richard : we could eventually make Big Bear foam tires as well

😉 I exactly thought to the coors when I saw your cutting tool.

While I still have to deal with the foam tires, this morning the weather was good enough, so I took some time to paint the bodyshell
And yes, it won't be a Ferrari, but something else (thanks Yogibear for the stickers)

The work is not over, yet : I still need to take care of the driver and the mirrors... And as well, finish the electronics installation (not yet done on this chassis).

French design, french build and french deco. Michel Vaillant 👍👍👍 I love it. Maybe in a near future a french designed and built body???🧐

1/12 driver is so small... I decided to cheat as I did not want to paint the face... The body is a Hunter driver body scaled 80% and the the helmet is the one I did for the Super Wheelie, scaled smaller than 80%... Not sure how much I scale it down, but it is small.


The driver is in the car now...

I have plans

As mentioned earlier, I have many plans for this chassis in terms of bodyshell...
And by the way, if you build one chassis for you, and work out a bodyshell adaptation you are putting on makerworld, let me know so I can add a link into the dedicated pancar 1/12 collection

I started to work on the Ferrari 312 bodyshell... This one may be red .
As we are dealing with endurance cars, lights is a must, and some 312 had central additional lights, so I plan for it (not sure if I'll use them or not, but it will be possible).

The rear bodymount is a variation of the one I made for the 333 bodyshell...

I printed those in TPU.




I still need to work out the rear end, as I'm not sully happy with this...


Once the parts under the bodyshell are done, I'll work out what is on top of it...

I spend some time over the week-end to work on this bodyshell... It's not perfect yet and still requires some minor improvements... I finished the part under the bodyshell...


As last time, I printed something to help the arch cut at the rear (on the front it is not needed on this Sabula Tech bodyshell)


And once this was done, I made a mirror and a roll bar...


It still requires a bit of work with some adjustments here and there, but we are getting there...






Soon it will be time to deal with the next bodyshell (teaser : Porsche 917K)
