Z-axis lead screw cleaning tool (1/4" socket)

🔴 READ BEFORE USE – IMPORTANT SAFETY INSTRUCTIONS 🔴

⚠️ This tool may ONLY be used under the following conditions:

• ✅ Printer MUST be completely disconnected from power
• ✅ Z-belt MUST be installed and correctly tensioned
• ❌ Never turn individual Z-leadscrews without the belt
• ❌ Do not use high speeds
• ❌ Do not force it to the mechanical stops

👉 The Z-axis of Bambu Lab printers is moved by three leadscrews, synchronized by a common belt
Turning only a single leadscrew (e.g. without the belt) can lead to bed misalignment, tension, or mechanical damage

👉 Use cordless screwdriver exclusively at very low speed, to:

• avoid excessive induced voltage in the stepper motor
• keep mechanical stress low

Use at your own risk. It is better to use a hand-driven tool! See last image

🛠️ Description

This 3D printed Z-axis leadscrew adapter with 1/4" socket connection was developed to turn the Z-leadscrews of Bambu Lab 3D printers easily, controllably, and without effort

The adapter is placed onto the Z-leadscrew pulley from below and can be operated with a cordless screwdriver at a very low speed
This allows the leadscrews to be conveniently turned with the printer unplugged – ideal for cleaning, visual inspection, and lubrication of the Z-axis

✅ Compatibility

Suitable for the following models (identical or very similar Z-axis construction):

• Bambu Lab P1S
• Bambu Lab P1P
• Bambu Lab X1
• Bambu Lab X1 Carbon

💡 Note: Should also work with other Bambu Lab models like P2S, provided the Z-pulleys are identical. I look forward to your feedback on this!

🧼 Purpose

• Even turning of all Z-leadscrews for cleaning
• Removing dust, abrasion, and old lubricants
• Easy and clean application of lubricant
• Maintenance without manual cranking or effort

Perfect for regular maintenance and improving the smooth operation of the Z-axis

⚠️ Detailed Safety Instructions

❗ ALWAYS disconnect the printer from power

• Turning the leadscrews can generate electrical voltage through the stepper motors

❗ Only use with Z-belt installed and correctly tensioned

• The belt connects all three Z-leadscrews
• Only this way is it ensured that the print bed moves synchronously and without tension

❗ Use very low speed

• Ideally use hand-driven
• Cordless screwdriver only in the slowest gear
• If necessary, use torque limitation at the lowest setting!
• No impact driver!

❗ Do not use force

• Stop immediately if there is resistance
• Do not drive it to the mechanical end stops

🖨️ Print Recommendations

• Material: PLA+ recommended
  (PETG, ABS, or ASA also possible)
• Infill: ≥ 25 %
• Walls: at least 4–5 perimeter
• Print orientation: Socket side up for maximum stability
