TORQUEY - Prusa XL Edition - Torque Wrench for Nextruder Nozzle

Finally! A torque tool for the Prusa XL Nextruder nozzles. Never overtighten or undertighten your nozzle again.

Hello Makers,

This is a fully 3D-printable torque wrench for the Prusa Xl Nextruder. No extra hardware required.

This is a Remix. The Original is from @Perinski <3
I created this remix because I didn't have any magnets on hand, and they're actually unnecessary if you can print accurately.
You can also now simply apply pressure to the screw with the torque wrench without it falling apart.
The cover can now be easily clicked into place and removed again to insert a different torque socket.

Works with every 1/4" Inch hex.

Print settings:

Before printing all the inserts, you should print just one to test that it fits. If you can't get a 1/4" hex bit in, you should reduce your flow. If it's too loose, you should increase your flow. It's best to just do a flow test beforehand.

I used for my Tests dried Prusament PETG. If you want to get the most consistent values, definitely use PETG. Preferably the one from Prusament. If you want to support me, you can use my code when purchasing Prusament or a Prusa Printer at the Checkout. Its a Win-win ;)

My Prusa P2P Code: @INVESTEGATE

If you want to use other materials: I recommend to use PETG, ABS or Nylon. Dont use glitter or carbon stuff!

• 0.4mm nozzle
• 3 Perimeters
• 50% Rectilinear Infill
• 0.2mm Layer high.
• Supports only for the Rotor Inserts
• Maybe you need a brim.

You can also use my preconfigured 3MF file. Its 100% configured like in my Tests.

Tools i used:

• 1/4" Inch Hexbit Long T8: https://s.click.aliexpress.com/e/_oEsEd3T
• or 1/4" Inch Bosch Hexbit Long T8: https://www.amazon.de/Bosch-Pro-Extra-Hart-Innen-Torx-Schrauben-L%C3%A4nge/dp/B004ALFVJA
• Square to Hex ¼Inch: https://s.click.aliexpress.com/e/_op5P7X3

Instruction:

The Nextruder nozzle shaft is attached to the Nextruder with a T8 screw. Prusa specifies a torque value of 0.2-0.3nm.

You can now choose the following torque strength for the T8 Nozzle mount:

• 0.7mm: 0.25 - 0.35nm
• 0.8mm: 0.35 - 0.45nm

I've tested both thicknesses without any problems. However, I recommend using the thickness recommended by Prusa. So, use the 0.7mm rotor insert.
If you want something a little firmer, you can also use the 0.8mm version.

---

For screwing the Nextruder nozzle to the hotend with a 7mm nut, Prusa specifies a torque value of 1.5nm.

You can now choose the following torque strength for the 7mm nut connection:

• 1.2mm: 1.5 - 1.6nm
• 1.25mm: 1.7 - 1.8nm

I've tested both thicknesses without any problems. However, I recommend using the thickness recommended by Prusa. So, use the 1.2mm rotor insert.
If you want something a little firmer, you can also use the 1.25mm version.

How i measured it:

Since I don't have a special measuring device to accurately measure torque, I simply used my adjustable torque screwdriver from the company Wiha. I then connected them as shown in the picture above and painstakingly measured everything. So the measured values are still relatively accurate.

PS: Unfortunately, one of the three Wiha screwdrivers gave up the ghost. So if you're happy with the project, I'd appreciate a small donation <3
