This is the OpenR/C Formula 1 car. It´s the third generation OpenR/C car and this time around focus is on simplicity! You can print everything in PLA except the tires which are done in NinjaFlex! Of course you can print it in any material you like but for those that want to print a car but only have PLA at hand, this is the project for you!

A note on the servo saver. It´s designed to be used with PLA, the upper and lower BOM applies force similar to a spring in a convetional servo saver. Of course the pressure depends on the type of material used, infill etc. Fine tuning can be done adding washer under or over the servo saver.

The "Main Turning Vane´s" needs to have it´s lower part trimmed using a "exacto knife". Then slide it in the chassie plate and push it over the "Lid" and it should snap into place-

Parts that need support added:

Front Spoiler.stl


Rear Rim.stl

Rear Wing.stl

Servo Saver Lower.stl

Things to buy:

Ok, obviously you need some filament which you´ll get from your favourite filament supplier.

You also need M3 screws and nuts which you can get at your local hardware store. Check the BOM list for what to get.

Some bearings are needed aswell, check the BOM list or buy a kit from FastEddyBearings.com: http://www.fasteddybearings.com/openrc-f1-sealed-bearing-kit/

Last but not least you need electronics and here´s what i got, all from HobbyKing:

ESC and motor combo: http://www.hobbyking.com/hobbyking/store/__65982__TrackStar_ROAR_approved_1_10th_Stock_Class_Brushless_ESC_and_Motor_Combo_21_5T_.html

Battery: http://hobbyking.com/hobbyking/store/__23134__Turnigy_nano_tech_Shorty_4200mah_2S2P_65_130C_Hardcase_Lipo_Pack_ROAR_APPROVED_.html

Micro Servo This is what i bought and i think it´s not very good, please let me know if you have a better revommendation. http://www.hobbyking.com/hobbyking/store/__7472__Turnigy_8482_TGY_1800A_Servo_1_5kg_0_10sec_8g.html

Transmitter and Receiver (i use something else but this is a "cheap" alternative): http://hobbyking.com/hobbyking/store/__83360__HobbyKing_174_8482_HK_GT2B_3CH_2_4GHz_Transmitter_and_Receiver_w_Rechargable_Li_ion_Battery.html

If you are new to this whole R/C hobby you´ll also need a LiPo charger for the battery. Ask in the Google + Community for recommendations: https://plus.google.com/u/0/communities/112745535856143176146

This is my first project and it came out great. I'm new into 3d printing I'm using a Ultimaker 2 with olsson block hot end I've put a few hundred hours of printing on it now. I have showed my formula F1 to many people and I carry a failed wheel and tire and the reaction I get from people is awesome. Daniel Norée thank you for your letting me learn on your AWESOME design. Thank You Gerry

Thank you very much for you comment, it´s so nice to hear that you like it. Thank you for putting in all the work of making one yourself! Thank you /Daniel

How fast can it go? what would be the total cost of the project? I have my own transmitter (turnigy 9x)
Have anyone tried to put and FPV camera on it??

Top speed depends on gearing ratio used. With the "stock" setup and recommended electronics it reach about 35km/h. I´m working on releasing more variations for gearing ratio. My current setup goes at 40km/h but i´m aiming for something like 45-50km/h.

I have a 5300 kv motor and right now on my rc truck it goes 50 mph would that be to big of a motor?

Thanks, nice work, after I finish an FPV project with a 250mm quad, (80 km/hr) i will engage in this model.

What are the different settings to print this? I'm using Cura. Thanks in advance

i'm mostly using 0.2 layer height, 100% infill for stress parts, and 10 tor cosmetic parts.

Thank you, I have been using .25 and anywhere from 50% to 100%. I may try to print .2 on some of the other parts I have left to print. Still need to get the motor and esc for this project. I have all kinds of Airplane motors and escs, but nothing for rc cars.

anyone able to print me a set of tires? im willing to pay ya.

Where are you from??

Try the OpenRC Community on G+ or the Facebook group, i´m sure there´s somebody willing to help.

Does any one know the final product in grams?

How much ninjaflex do i need to buy to print these tires? There's 2 purchasing options on amazon.com, the 50g spool or the 500g spool. What's the printed weigh per tire (roughly)?

It really depends on the density of the wheel you print. 1 wheel at standard quick print settings (Cura) will use 22g of material.

So instead of using ninjaflex for the tires(god is it expensive) could i instead use the flexible tpu by sainsmart? its supposedly not as flexible as ninjaflex but still pretty flexible.

TPU will more then suffice, depended on brand!

That could work but make it as flexible as possbile since there isn't much suspension (none actually) to cushion any pebbles on the track.

Anyone know if these rims are standard size? I don't have the ninjaflex to make the tires and I really think just buying some tires would be better and probably much cheaper.

I love r/c's just as much as the next guy/gal. But has anyone tried printing this just as a nice model? Put on a desk or something.

Probably better off, for every 1 minutes of playing outside I spend 1 hour printing parts that I broke off in that 1 minute.

So it would be possible to skip the "internal parts" and just print a shell of the car for display?

Yes! Desk Model was the first thing I did, slightly scaled down

I'm going to remix this so I can put a rocket engine in it.

That would be awesome if you did! =)

I don't know how to make front bom assembly.
Can you show me the picture?

What infill do you use with the tires? I've never printed in Ninjaflex before so this part is all new.

twlum - in reply to twlum

I eventually settled on 10%-20% infill but you need 5 top layers since the ninjaflex doesn't fill in as nicely without a lot of support for bridging.

nice job! you did ask if there was a better servo and i thought i might share here is my go to servo http://www.hobbyking.com/hobbyking/store/__17322__Turnigy_8482_TGY_9018MG_MG_Servo_2_5kg_0_10sec_13g.html
it has worked for me for years only one ever had a issue. due to a minor scrape landing to fast. very strong and fast. super precise movement and really good centering every time. hope this helps someone.

That's awesome, thanks!

Looks beautiful!

Why no differential? Thing must be a bear to drive without!

I don't suppose anyone has developed a version of the larger parts that can print on a 150x150 build plate, like someone did with the truggy?

So far, I have only printed the nose and Front_Lower. Beautifully designed, well thought out project from someone who has actually used a 3d printer. Parts appear to all be aligned well for printing, and assembly. I can't wait to finish this.

I have all the large external pieces done. Some are a very tight fit. Make sure your printer is well calibrated. It's coming together nicely. Printed the flat chassis pieces at .3 layer and they worked much better than the attempt at .1

Bill of Materials is missing M3x12 cap screws for motor mount. Otherwise an amazing project!

This thing is sweet!!! Going to start printing parts tonight:) great job on the design!!!!

congrats on the feature!

I love this design. It'd be great if you could post some photos :D

Without going through the full BOM myself, how much did you spend on all the internals? Also maybe an approximate plastic usage. Thanks.

Where did you get the tires seen in the 3rd picture?

was it printed using NinjaFlex?

what is the wheel base dimension? and width?
Looking for a 1/10 scale car for another body?

For those of you looking to put one of these together, we are selling the fastener and bearings kit for this 3D Print on Etsy.

Bearings - https://www.etsy.com/listing/263816863/openrc-f1-bearings-kit-for-3d-printed-rc
Fasteners (screws) - https://www.etsy.com/listing/265443380/openrc-f1-fastener-kit-for-3d-printed-rc

Me and a friend both purchased a set of bearings and screws. We received combined shipping and it was pretty quick as well. The bearings are super smooth. Thanks again for making these kits, my local stores do not go lower than M4 for some odd reason.

Tldr: I recommend.

what size foam tires and who would you recommend buying the foam tires from?

Currently there are no rims for foam tires i´m afraid.

If only there was a device that we all owned capable of manufacturing anything we wanted... ;P

What scale does this car have, and with the reccomended non-printed parts, how fast does it go?

Scale is 1:10, don´t know about the speed, i haven´t measured it.

Thank you very much for your inspirations! I'm going to build my own RC-car (I'm more interested in building everything myself, rather driving the final product :) ).
Maybe some useful information for you:
I've done my first test prints on PETG-filaments and the results are just amazing compared to ABS (not talking about PLA). Total strong, heat resistant, no warping and flexible. I see you are living in sweden, there is a e-bay shop in the netherlands for cheap PETG-filaments: http://tinyurl.com/zqlkk3p
Price is about 23 Euro / kg, so really cheap. Main advantage of PETG: Easy to handle like PLA: fire up extruder to 220-240, heatbed to 70, done!

What infill percentage do you recommend?

I have printed the body at 20% infill, rear axle and gears at about 50%. The rear and front wing 100%.

My other suggestion, would be another nut and bolt pair between the front and center, further up and more to the outside to improve the fit between those two shell pieces at the edges of the air intakes (might add more vertical stiffness along the length of the car). This may accommodate better any imperfections or curvature between the intake pieces.

I am printing this in ABS. Either my printer produces slightly small printouts, or the clearances for the 3mm nuts is very tight, as I found that the RTL Fasteners nuts I'm using are just a little too big for them (in thinkness, and width). You might want to resize those holes up by .5mm or so to add some safety margin for hardware variances. I'm working around this issue in the existing prints by using m2.5 hardware nuts and bolts instead.

FwA - in reply to dragosr

Abs shrinks after printing. Pla expands

ssrjazz - in reply to FwA

PLA does not expand. It shrinks, just not nearly as much as ABS

Beautiful x-mas decoration.

Great Christmas gift Daniel. Thank you.

Your welcome! =)

Yet another amazing RC model Daniel! Thanks for sharing! :)

Hi Daniel
You done it again. Now I have to choose between my ferry projekt or start with printing your F1 car. I must have a printer no 2.

Thanks Torben!

Having two printers (or more) is a great thing! =)

I have printed almost all of the parts for this and I am having some alignment issues with the main chassis, The holes don't line up with the body if I snap the 2 pieces of the chassis together. I am not sure if it is a problem with my printer or if other people have had this problem.

Thanks for letting me know. I´ll have a look.

same problem the two chassis fit together but the body parts do not line up

Ok, thats weird. I downloaded the stl's and they seemed to fit. Would you mind posting some pics in either the Google community or Facebook group? I would really appreciate it! Thanks!

How can I get you the pics of the formula 1 chassis
