Hello friends,

because there is no available model of Rover Vitesse in 1:24 scale, I decided to 3d print one for myself.
First step was to model it. It took quite some time and the result looks like this:

To make sanding and filling easier I decided to split the car to parts. Here is first print on FDM printer. Thickness is 1mm (1,5 - 2mm in crittical places like fenders and columns):

I did not like support of the parts generated by the slicer, so I modeld my own. This is how it looks before support removal, straigth from the printer:

Here is the body assembled and ready for crash test. For crash test I put together chassis from parts I found at hand.

I was affraid of durability of 3d printed body, but after crash test I was pleassed with what it endured, It handled usual crashes without problem. After direct hit to the wall at quite high speed (on purpose) it just brokoe in one place. I thought it will break to thousand peaces, so i was pleasantly surprised. Here is repaired car after crash test. It broke on places that are glued - hood and fenders:

Last progress are lights. I am trying two approaches. One is to make the plug and make the lights by pulling melted plastic over that, and second is to print it with clear PLA. I think I will use printed lights. It has the texture almost like original light and is in final shape straigth from the printer:

Now I will print final version of the body and start to fill and sand to make it smooth.

Thank you, I can not wait too :). I must figure out where to fill and sand the thing. All the places that I can use are realy cold now, in the winter. No heating there.

This is how the chassis looks like. It consists from three separate parts - motor pod (sidewinder configuration), guide holder and chassis. I aim for realistic look, so the chassis clearance is in scale to the original, only the motor pod is 2mm from the track to bring the weigth of the motor closer to the track.

Sanding has started.

After the print:
1. I sprayed two layers of filler/primer
2. I sanded with 220 grit sandpaper until plastic has shown up
3. I used "superglue" gel as a putty to correct small errors in print, mainly missing/not aligned layers on edges.
4. I sprayed one layer of filler/primer.
5. I smoothed with 320 grit sandpaper if needed, but not let the plastic show throught.

Results after different steps from this list are marked on this image:

Very nice work.
We find that 0.6 - 0.8mm makes a body thick enough to survive but light enough to be raceable. Three coats of prime and sand sounds about right. The car looks good, and if you made your own file that's even better!

I like how you said "1st step model it" Very impressive modelling :)
I hope to one day have the skills to do that so I can make a model of the AC A98 Cobra Coupe car - but at the moment I am sticking to smaller projects.

Thanky you for comments.

Red colour on the photo is more orange due to yellow ligts in the room. I hope I get the red colour right enought. Do you know the exact shade of the red?
