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

Front.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

Howdy, I am trying to find a picture of without the top parts on so i can see the exact layout of the electronics, can someone please post a pic like that for me? or link me to a picture... i know the pdfs show most of it... but i am trying to figure out the the position of the esc

would you recommend using Filaflex for printig the tire_v2? which infill do you recommend?

Here´s a video where i talk about how i print the F1 tires (V2): https://youtu.be/GRyA-5lrgd0

Awesome design! Printing one atm. But want to use The electronics i have laying around. But it's 1/14 scale. Can you upload The motor mount CAD Files. So i can try to mod myself?

Just download the STEP file of the entire assembly and your good to go! =)

Ah! thanx =)

That was fast! =)
Good work on the mount!

Hehe thanx! =)

I know people use different fill rates, but on average, how much PLA could I expect per car? I'm interested in building 6-8 cars to use in my freshman-level transportation class. The only things we won't be printing are the rear axle and gears since we'll be machining those items in the machine shop to help meet some of the state standards. I'm going to print one entire car though as "prototype" before we start changing items like the rear axle. That leads to the first problem.

Also, we have a Flashforge Finder in the classroom and I haven't encountered any warping on it before, but I started printing the rear axle today and about 5-10 minutes into the build the ends started curling up off of the bed. The center section and the first to steps outside of it look great, but the two smaller diameter sections curled up enough that its not usable. Any tips would be greatly appreciated.

I don't have a large enough printbed to print the chasis front and back (PB Simple 150x150x150) so I sliced it and used a heat gun to melt/weld/solder it back together. I wish I knew how to slice it to make it into interlocking pieces instead of one straight line. If anyone is interested, I can link the sliced pieces or if someone can actually cut it into some of interlocking design, that would be awesome

Is this what you are looking for? http://www.thingiverse.com/thing:1680470

Split Chassis (for smaller build plates)

Wow, yes, I wish I had seen that before. I used a free netFab trial to cut straight lines but I'm not sure how to cut lines like that. I see the guy used Tinkercad to do some modifications, what do you use Daniel to make those cuts? Here are some photos of the cuts 'welded' together. It's ugly but it was just a test to see if I can melt parts together and see if I can melt more PLA to hold the seems together. Don't really care about the aesthetics, as long as it holds well and fits together so far it is.

Ah, i agree with you, as long as it holds together it´s fine! =)

I use Fusion 360 to maker those cuts. (The entire car is done in Fusion 360)

This car is the most polished FDM model I've ever seen. All tolerances are perfect and don't require trimming or resizing to get things to fit. Amazing! Almost every piece is designed to print without support, absolutely superb!

Thanks man! I´m glad you like it! =)

Hello all. I am building the OpenRC F1 can and cant seem to find any Tires! looking to purchases some asap. Good Year or Pirelli.. please help. im in the UK. What Tires would just fit this rim size if bought?

Hi, I now have the TAMIYA F104 Rubber Tires, but to large for the original STL Rim that i printed. cant find a scaled rim design? any advice?

Is it the front rim? Apparently there are different versions of the tire. I will look into this. I do think these will fit though, have a look: http://www.thingiverse.com/thing:1462917

OpenRC F1 Rims for Tamiya Tires

My printer can't print flexible filaments. Would there be any tires I could substitute the wheels with?

Hello,

nice car, could someone make a pic like the front axis is mound with the servo ?

I'm totaly new in building RC things, but i just wanna try it, is it hard to build it? Just don't wanna waste that money :X

How is the servo connected to the servo saver?

Use a metal wire of some sort. I use 1.5mm Alu pin

someone had this car in their booth at the maker fair of san mateo, california. It was in a semitranslucent blue. It was really cool to look at.

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

i olso use ultimaker 2

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.

Have you played around with boost and turbo on the ESC?

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://tinkermake.com/product/openrc-f1-bearings-kit-3d-printed-rc-car
Fasteners (screws) - https://tinkermake.com/product/openrc-f1-fastener-kit-3d-printed-rc-car

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.

Awesome just saw this! Thank you!

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.
regards
Torben

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.

I'm having the same issue. Did this ever get addressed? I've printed the body a couple times in pla. I printed the chassis in PETG. If I force the chassis and body holes to line up, I break the front of the body.

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
