The advantage having a Bambu Lab X1C, it is quite quick to print such part... And it lines up perfectly, as expected...


I've also set a part for the dashboard...

Looks good. Is the MJF PA12 printing expensive?

It definitely depends where you get the parts printed... (spoiler : shapeways is by (very, very, very) far the most expensive...). That being said, in the current case, and due to the work I did on this project, I felt it was mandatory to have a show car from this (but it would be probably less expensive to find a Super Wheelie in good shape)...

I'm happy to report that my masking plan worked as expected.


And the result is here... It's not perfect, but I'm quite happy, and the stickers will work (whenever they arrive)...



Still have to work out the leds circuitry, to paint the driver (it is going to be long), and deal with the details on the bodyshell and the dashboard...

I worked a bit on the driver, I will have to find a better driver or a better solution at some point, but for the time being, it will do the job... There is still a lot to do on that one...


I also worked out the accesories, and the transluscent ABS snap on lenses fit the bodyshell like a charm, giving it a look closer to the original lenses... I also paint the embossed (unperfect) logo...


I conducted a few prints, with additional ideas... A locker to avoid using glue for the steering wheel support


A new approach for the leds on the roll cage, which is much better than what I had in mind originally and this will allow me to hide the wires a bit...


And beside this, I also added some details to the bodyshell with paint...



I need to finalise the led circuitry path and additional locks for the rear and front leds, and finish the driver paint job...

Bouncing Billy starts to get really impatient, now...

I was pretty busy those last evenning to finish this... There is an event this week-end and I wanted the bodyshell to be finished (stickers aside, which will be later on)...

The work is almost done. I identified a few elements for correction, but they are very minor, and they are all noted in my todo list. It's really a pleasure to be able to see the car finally complete and in a painted non CAD glory...


And the lights are working...




The cable of the battery is not organized properly, but there is room inside to make it nicer..




Once the solo pictures were done, I had to do a bit of familly pictures...

With the old CJ-7 brother...


And with the Big Bear as well








Bouncing Billy is not yet strongly attached to the body shell, I need to find a solution for this as I suspect the resin won't resist a run...

There was a few Super Wheelies present in the event over the week-end...



The Mitsubishi Jeep catched the people and generated a few 3D printing discussions, but I did not ran it. I won't run it until it has stickers on.

The CJ-7 however ran, like the Big Bear and a few times... In the afternoon, my brother was there, and he kindly took some video footage (I just removed the embarassing crashes from the video :-) ).

The behavior of the Super Wheelie is as predictable as you can imagine (especially now that I don't retain the horses anymore) : the springs are providing the nice lack of precision on the front end while the tend to generate wheelies easily on the rear end (the spacers are not present, otherwise the car would be even doing more wheelies)... In short, unpredictability is the main quality of this car in its original form :mrgreen: ... Normally, the shocks should change the things a bit :-)
