Prusa CORE One+ Gen 2 nozzle wiper holder

Prusa CORE One+ Gen 2 Nozzle Wiper Holder

A community-made recreation of the Prusa CORE One+ Gen 2 nozzle wiper holder , designed to work with the native Prusa firmware cleaning routine .

This is not a remix or modification of an existing nozzle wiper model . I designed the entire holder from scratch using:

- nozzle-cleaning positions and movements found directly in the Prusa firmware,

- available CORE One CAD data,

- reference photos of the original Gen 2 nozzle wiper,

- my own measurements,

- physical testing on the printer.

The goal was to reproduce the functionality and mounting position of the original Gen 2 solution as closely as possible while keeping compatibility with Prusa's native firmware routine.

Why I made it

I ordered the official CORE One → Gen 2 upgrade kit when the estimated delivery time was approximately 3 days .

After placing and paying for the order, the estimated delivery was pushed back by roughly 5 weeks .

Since I already had firmware 6.8.1 installed, which includes support for the new Gen 2 nozzle wiper, I didn't want to wait another five weeks just to use this feature.

So I decided to design the holder myself.

Firmware compatibility

Designed for Prusa CORE One / CORE One+ with firmware 6.8.1 or newer compatible firmware .

After installation, enable:

Settings → Hardware → Nozzle Wiper

The native cleaning routine can also be manually tested using:

G12

No custom start G-code, modified cleaning coordinates or custom wipe macros are required.

The printer uses the native Prusa nozzle-wiper routine.

Installation

The holder is designed to be installed in the same location and in the same way as the original Gen 2 nozzle wiper shown in Prusa's official CORE One → Gen 2 upgrade instructions .

For the physical installation, I recommend following the official Prusa Gen 2 upgrade guide.

The assembly also uses an expansion joint next to the wiping area , just like the original Prusa Gen 2 solution.

The expansion joint acts as the fixed nozzle touch/reference point used by the cleaning routine, so its position is important for correct operation.

Required parts

You will need:

- the printed nozzle wiper holder,

- silicone nozzle wiping insert/pad,

- expansion joint,

- M3 hardware used for the Gen 2-style installation.

The design follows the same basic mounting concept as the original Gen 2 assembly.

Printing instructions

IMPORTANT – printing orientation

Do not use the orientation stored in the STL file as the printing orientation.

I accidentally exported the STL in the wrong orientation.

Before slicing, rotate the model so that the large flat side of the holder is placed directly on the build plate .

This is the intended printing orientation.
