Printable parts for Original Prusa

This article is also available in following languages: 

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

The naming of printable parts

To know the origin of our printable parts, the names of the parts always start with an alphabetical letter followed by a number. The identification can be found in larger parts. In smaller printed parts where the identification does not fit, dots and squares are used. It starts with a single dot, the number of dots corresponds to the serial number of the version. Squares are used for custom plastics. It starts with one square, the number of squares corresponds to the serial number of the version.

• A/B/C/D/dots/triangles: Parts printed in the Prusa Farm sent with the printers or found at our e-shop.
• R/S/T/squares: Parts that can be found at Prusa Research profile at Printables, Prusa3D site or our Github. These are the parts you can print yourself.

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

You can download STL files for 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: 15% 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.

Project files (STEP/SCAD)

We do not provide the actual project files for our printed parts. Too many different programs are 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.

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.
