Printable parts for Original Prusa

This article is also available in following languages: 
CSDEESFRITJAPL

Plastic parts used on our 3D printers are printed by the same very machines, holding on to the original idea of the RepRap project. If you want to print replacement parts, upgrades, have your printer in a different color, or make your own modifications it is all available online.

Downloading printable parts

Printables.com

We have published STL files for every printable part of our printers, as well as printing instructions, to Printable's print depository. Here you can easily browse and view parts by their area of installation using the Printables folders feature.

Check out the Printable parts collection on Printables to find the parts you need.

Prusa3d.com

You can find the latest printable parts for all of our 3D printers or printer upgrades at Prusa i3 Printable parts. Printable parts are divided into two groups: 

  • Complete kits - which contain a full set of plastic parts for the entire 3D printer.  
  • Upgrades - which contain only the parts for upgrading to the new version of the printer. 

Here you can download STL-files for absolutely all plastic parts and pre-sliced GCODES for all upgrades.

Settings

If you decide to generate your G-codes, it is recommended to use:

  • Material: PETG
  • 0.2 mm layer height QUALITY preset
  • Infill: 20% GRID

The 'Fan-shroud'- part, which directs air from the print-fan to the part, should be printed in ASA or ABS, but otherwise with the same settings.

If you have printed your own plastic parts, check this article for guidance on post-processing.

Project files (STEP/SCAD)

We do not provide the actual project-files for our printed parts. Too many different programs being used for that. However, if you are interested in modifying the parts we have made STEP files (in addition to STL files) available on our Github, for all parts.

Project files (STEP/SCAD) are only available in the Github branch/tree where they were initially released.

Some parts were designed using OpenSCAD, where SCAD files are the project files you can edit. For that reason, for all parts designed with OpenSCAD, there are only SCAD files and no STEP-files available. This also includes metal parts.

For the MK-series you simply select the branch for the machine you are after and navigate to the file.

The naming of printable parts

To know the origin of our printable parts, we are using naming which always starts with an alphabetical letter and is followed by a number

  • C# D# - MK3S/MK3S+ parts produced in our 3D printing farm, which are sent to our customers with Kits or pre-assembled printers. 
  • F# - MINI / MINI+ parts, farm printed. 
  • M# - MMU2S parts, farm printed. 
  • S# - SL1 / CW1 parts, farm printed.
  • R# - Parts that can be found at Prusa Research profile at PrusaPrinters, Prusa3D site or our Github. These are the parts you can print yourself. 

Each letter of the alphabet is only used 9 times. For example, once we reached C9, the next revision was named D1.
