Completely optimised for FDM 3D printing, I bring you this time a lovely classic Porsche 911 Turbo (930) from 1975.

The main body has been designed as a 1.6mm shell to be printed with four 0.4mm perimeters with minimum supports. It has been divided into 3 main parts plus the front and rear bumpers and the lower sides. Those seven parts are connected with M3x8mm screws, giving as a result a quite rigid body.

The wind-shield and side windows can be printed in transparent plastic and glued, while the rear window is part of the rear main part to make it easier to print without the need of tall supports.

All these main parts require minimum supports, which means you will just need to support them in the first layers until the base of the part is fully reached. This will save a lot of plastic compared to other ways or orientations of printing it and will keep the surface finish quite more clean, due to the fewer retractions needed in each layer.

What about the size? I decided this time to build a 1/9 version instead of my preferred 1/10 version, as the real car is very small. If I would have kept the 1/10 scale, I couldn't use MyRCCar KIDS chassis, which minimum wheelbase is 250mm and the shortest width is around 180mm. Instead, at 1/9 scale it perfectly fits the chassis and the actual available CVDs for that chassis.

If you want to build it with MyRCCar KIDS Chassis, you will need different CVDs for the front and rear axles. In this vehicle, the rear axle is quite wider than the front one.

I used this 44mm CVDs for the front axle and this HSP 102015 CVDs for the rear axle.

The printable design includes a few holes for the lights. You will need 5mm LEDs for the front and rear white/red lights and 3mm LEDS for the blinking lights.

The design has some extra details, as the door handles, rear-views, wind-shield cleaners, front light water jets or motor grills. If you wonder where all these great detailed parts come from, I made this 3D printable design based on the model from great designer Karol Miklas, which is one of the most detailed models I have seen out there, specially in the texture chapter, with details you can only see in certain angles.

The model is also provided at 1/10 scale, but the size of the holes for LED lights and screws is also scaled, so you will need smaller screws and re-shape the holes for the LED lights a little if you want to print it at 1/10 scale.

I printed the main parts in white and then painted them in some kind of musk green, but I would suggest you to print them directly in the main colour, as you will only have to paint after printing it the black details and a few extra colour for the transparent covers of the lights. Anyway, I'm sure you can do a better painting job than I did, that is really not one of my best skills...

If you like the model, remember to use the provided link to the original model designer to congrats him and let him know you like it.

Updated the files so now they include the "P O R S C H E" Lettering for the back, the fog lights and the side decoration.
