OpenRC F1 3D Printing Guide #

The most confusing thing for me when printing the OpenRC F1 car was “what parts do I need for which year, and what parts work across different years?”

The whole point of this page is to answer these questions. You can also follow links for each part to see details including:

• Link to download the part
• How much filament does it use?
• How long does it take to print?
• Does it require supports?
• How direction should it be printed?
• How does this remix compare to the original?
• Etc

Why is it confusing #

The original car (referred to as 2015) was released with all parts. The 2017 version has a wider wheelbase which required many updated parts, but various pieces were still reused from 2015. Then 2018 and 2019 reused some parts from 2017 and others from 2015. And then you have hundreds of remixes since its release, many of which don’t specify which version they’re meant to be used on (note: I absolutely have no intention of listing every remixed part; not even close! I have only included remixed parts that I have personally printed).

How to use this parts list #

Part numbers #

I have created part numbers in order to make it easier to reference specific parts.

Sections #

The car is broken up in to 7 sections:

• Chassis (CH)
• Front axle (FA) – includes parts that attach to the front axle
• Rear axle (RA) – includes parts that attach to the rear axle
• Drivetrain (DT) – includes all printable parts needed to make the “RC” part function
• Body (BD)
• Aero (AR)
• Wheels and tires (WH)

Each part number first starts with something to indicate which section they’re for. For example: DT-## for drivetrain parts.

Unique letter per part type #

Within each section, separate types of pieces are assigned a letter (in no particular order).

• Example 1: DT-D# for the pinion gear and DT-E# for the steering push pin.
• Example 2: BD-D# for the motor cover and BD-H# for the left side rear view mirror.

Unique number per version of part #

Then each type of part receives an incrementing number for different versions. All of them start at 1 for the original 2015 piece.

• Example 1: DT-E1 is the original 2015 steering push pin while DT-E2 is the 2017 version.
• Example 2: BD-D1 is the original 2015 center lid. BD-D2 is a remixed version that is vented. BD-D3 is the 2017+ center lid (required to fit the sharkfin). BD-D4 is a remixed version of the 2017+ version.

Picking your parts #

The part numbers I created should be used in the following ways:

• You should not print two different numbers of the same part letter (unless you’re trying different parts out on purpose)
  • Example 1: BD-B1 and BD-C2 is perfectly fine because BD-B# is the front of the car and BD-C# is the center body, but BD-B1 and BD-B2 doesn’t make sense because it’s 2 variations of the same part (BD-B#).
• You need to print (almost) every part letter on the list, but not every part number
  • Example: You should print BD-A1, BD-B1, BD-C1...BD-J1 but not BD-D1, BD-D2, BD-D3, BD-D4 (again, those are different variations of the same parts)
  • The exceptions to this rule are parts that aren’t necessary if you aren’t using electronics, and for parts that ONLY exist in certain years (currently limited to the halo and turning vanes)

To decide what to print you should:

• Locate all the parts based on the year car you want to print
  • In a lot of cases you can mix and match years. If a part says 2015+ then you can use it on ALL years. If it says 2017 then it can ONLY be used on the 2017. If it says 2017 then it can be used on all years EXCEPT the 2015.
• Determine if you want to use the remixed version for any of your parts. Make sure it’s the correct year still.
• Follow the link for each of your parts to find the download link and see helpful info on printing the part.
