After dropping my screwdriver the plastic stem that connects to the torque adjustment/on-off button broke off.

• Remove the torque indicator sticker at the back to reveal the screw that keeps everything in place.
• Printed at 0.2mm layers with 100% infill 
• I printed my replacement with DevilDesign Black ASA
  • The slightly softer material allows for a very tight fit (even without a screw)
• Not tested with PLA/PETG (might not print well without scaling adjustments for the ABS/ASA shrinkage the part was designed for)
