OmniaDrop V1.4

The OmniaDrop comes in four different versions.


The Standard version uses two mounting holes which are 60 mm apart. These mounting holes can be used to attach the OmniaDrop extruder to your 3D printer carriage.

The second version is a Prusa Edition which was developed to be a drop-in replacement for a standard Prusa i3 printer.

The fourth Version is the Ender 3 Edition which was designed by Elia Palme to be directly mounted on the X-carriage of the Ender 3, Ender 3 Pro and Ender 3 V2.

The fourth option has three internal threads that are 34 mm spaced apart equivalent to the Hemera Mounting option

Alternatively you can use the files of the OmniaDrop extruder and adapt it to your specific carriage.

All-Metal Heatbreak vs. PTFE lined Heatbreak?

The PTFE lined version of the Heatbreaks improve the print quality of highly flexible materials. Some very soft TPU/TPE filament are very "sticky" when they melt, so by lining the Heatbreak with PTFE it helps to improve the print quality of such flexible filaments. The downside of a PTFE lined Heatbreak is that the maximum printing temperature is 260°C. The all-metal Heatbreak can also print flexible filament reliably however your print settings needs to be tuned more precisely. So if you only print flexible filaments from time to time, then get the all-metal Heatbreak. If you want to print mainly flexible filaments then get the PTFE lined Heatbreak.

Which material are the parts for the OmniaDrop printed in?

The parts are printed in PC/PBT. This materials can handle ambient temperatures of up to 65°C. The PCB/PBT material option only comes in a black/white colour combination.


Which material  is used for the metal parts of the OmniaDrop?
The Hobbed Gears and Heatbreak are made from stainless steel. The cooling block is made from an aluminium alloy with a high heat transfer coefficient. The sun gear on the Nema 17 stepper motor is made from brass.

Are there any mounting plates for my printer?

There are some mounting plates for some printers on Thingiverse, however you will need to print these files:





Ender 5 plus:



Siderwinder X1:



Anycubic Mega:



Geeetech A10:


Ender5 modified with linear rails:


If you have designed a mount send us a link, please.

Are there any part cooling fan designs for the Volcano and Super Volcano?

Yes there are part cooling fan designs for the Volcano and Super Volcano hotend. These files are available from the download folder.

Is there a mirrored version of the OmniaDrop?

Yes there is, you just need to write "mirrored" into the comment section of your order.

Can you use a BLTouch on the OmniaDrop?

Yes, there is a BLTouch mounting option available for the OmniaDrop extruder.

Please be aware that no OmniaDrop Version comes with a BLTouch, you will need to source this sensor yourself.


Which filament diameter is better for flexible filaments?

Generally speaking, 3 mm flexible filament cannot kink in the extruder, while 1.75 mm flexible filament can. This is just due to the physical size of the 1.75mm filament. As a result, it is easier to extrude more filament per time with a 3 mm flexible filament than with a 1.75 mm filament. However, the print quality will always suffer if you print too fast regardless of filament diameter and filament material. Just work with that filament diameter you feel most comfortable with. Just be patient with flexible filaments and you will not see any big issues with either filament diameter.


Are there any differences between the 3 mm Filament and the 1.75 mm Filament version? 

The only difference between these two versions is the stepper motor and drive gears.


1.75 mm Nema 17 stepper motor

Body length: 20mm 

Weight: 140 gr.

Motor Type: Bipolar Stepper

Step Angle: 1.8 deg

Holding Torque: 13 Ncm (18.4

Rated Current/phase: 1.0A

Voltage: 3.5V

Phase Resistance: 3.5ohms

Inductance: 4.5mH ± 20%(1KHz)


3 mm Nema 17 stepper motor 

Body length: 34mm 

Weight: 230 gr.

Motor Type: Bipolar Stepper

Step Angle: 1.8 deg

Holding Torque: 22Ncm(

Rated Current/phase: 1.33A

Voltage: 2.8V

Phase Resistance: 2.1ohms

Inductance: 2.5mH ± 20%(1KHz)


It is possible to use the smaller Nema 17 motor with a 3 mm filament however, you will run into issues when extruding a lot of filament, for instance with a 0.8 mm nozzle printing at 0.4 mm layer heights. If you wish to use a the smaller Nema 17 with the 3 mm version, write that in the comment section when ordering.


Which OmniaDrop Prusa edition should I choose for the Prusa MK3?

Choose the OmniaDrop Prusa edition 24V and write in the comment section that you have a Prusa MK3 and that you need the 5V 3-pin blower fans.


Are there any downsides compared to the stock Prusa MK3 extruder?

The OmniaDrop extruder was built to optimally print flexible filaments and was not built to fit a certain printer. As a result, due to the design constraints on the Prusa MK3 printer you will lose 17.5 mm on the Y-axis and 7.5 mm on the X-axis however, this still leaves you with a print area of 242.5 mm in X and 192.5 mm in Y.

Currently the OmniaDrop does not come with a filament sensor, so you will not be able to use the filament sensor on your Prusa. The filament sensor on the Prusa could not be converted to fit the OmniaDrop extruder.

This is however a project for the future.
